Product basic information and core positioning

Product identification and series:

Complete model: 31H2S233

Series: Schneider Electric IASeries (The document title and content clearly relate to this series, presumably related to industrial automation or electrical control)

Product type: Based on parameters such as current, voltage, and wiring method, it is likely to be industrial circuit breakers, fuse holders, or wiring terminal products. The core function is to achieve safe connection, current control, or overload/short circuit protection of the circuit, and adapt to the electrical system requirements of industrial equipment.

Applicable scenarios:

The document does not directly indicate specific application scenarios, but based on the industrial properties and product electrical specifications of the IASeries series, it is speculated to be suitable for industrial automation production lines, mechanical equipment electrical cabinets, low-voltage distribution systems, and other scenarios. It needs to be used in conjunction with electrical components of the same series or compatible with them (such as circuit breakers, contactors, wires) to ensure stable circuit operation.

Key electrical specification parameters

The document focuses on clarifying the electrical performance parameters of the product, which are the core basis for selection and use, as follows:

Specific specifications for parameter categories

Rated current is estimated to be a specific value (such as 10A/16A as may be indicated in the document, which should be based on actual document parameters, based on similar products), referring to the maximum current that the product can withstand for long-term stable operation. Exceeding this value may trigger protection or cause damage

Rated Voltage: AC rated voltage, such as 230V AC/400V AC (commonly used industrial low voltage specifications), is suitable for the common voltage levels of industrial low voltage distribution systems and needs to be matched with the supply voltage of the application scenario

Wire Size supports a specific range of wire diameters, such as 1.5mm ² -4mm ² (copper wire). It specifies the cross-sectional area of the wire that can be connected to ensure that the wiring is secure and meets the current carrying requirements, avoiding heat generation caused by mismatched wire diameters

The number of poles is estimated to be 1P (single pole) or 2P (double pole) (based on the industry convention that “2” in model “31H2S233” may represent the number of poles). The number of poles determines the number of circuit loops controlled by the product. A single pole controls a single phase line, while a double pole can simultaneously control the phase line and neutral line (or two phase lines)

The protection level (IP Rating) may be marked as IP20 or IP40 (commonly used levels in industrial electrical cabinets) to indicate the ability of the product to prevent dust and solid foreign objects from entering. IP20 is suitable for cabinet installation to avoid direct contact with foreign objects; IP40 dustproof level is higher

Mechanical Structure and Installation Specification

Mechanical dimensions:

The document provides detailed mechanical dimension drawings of the product (such as length, width, height, and installation hole spacing), for example, the dimensions may be marked as “XX mm × XX mm × XX mm”, and the center distance of the installation holes may be “XX mm”, to ensure that the product can adapt to the installation rails (such as DIN rails, commonly used industrial installation methods) or fixed panels of standard industrial electrical cabinets, avoiding size discrepancies that may cause installation failure.

Installation method:

It is speculated that it is a DIN rail installation (the mainstream installation method for industrial electrical components), and the document may specify the installation steps: first align the product buckle with the DIN rail (such as a 35mm standard rail), press until the buckle is tightened, and ensure that there is no looseness after installation; If it is for panel installation, the diameter of the installation hole and the size of the opening should be marked to avoid panel damage during installation.

Installation environment requirements: It may be mentioned that the installation should be carried out in a dry, non corrosive gas environment with a temperature range of -20 ° C to+60 ° C (industrial standard environment), to avoid damp, high temperature or chemical corrosion environment affecting product performance.

Wiring method:

Clarify the method of wire connection to the terminal (such as screw compression type, plug-in type), for example, screw compression type requires the use of a specified specification screwdriver (such as PH2 Phillips screwdriver) to tighten the terminal screws, ensuring good wire contact and preventing looseness from causing excessive contact resistance and heating;

It is possible to label the wiring sequence (such as connecting the phase wire to the L terminal and the neutral wire to the N terminal) to avoid circuit faults or safety hazards caused by reverse wiring.

Security features and compliance certification

Security protection design:

If it is a protective product (such as a circuit breaker), it may have overload protection and short circuit protection functions. When the circuit current exceeds the rated value, the product can automatically disconnect the circuit to avoid equipment damage or fire risks;

The terminal part may be designed with an insulation protective cover to prevent operators from accidentally coming into contact with live terminals and reduce the risk of electric shock.

8502-BI-DP is a bus interface module (BIM) used to connect MTL8000 series nodes to Profibus DP host LAN. It has functions such as high-speed data transmission, flexible configuration, rich diagnosis, and support for HART protocol. It is suitable for communication connection between I/O modules and hosts in industrial control scenarios. The following is a summary of the specific content:

Core functions and communication capabilities

High speed data transmission: The local area network (LAN) can run at a maximum speed of 6M baud (6000kbaud) and can also collect I/O module data at high speed, meeting the real-time requirements of industrial control.

Data and Protocol Support: Supports Profibus DP protocol, which can be used to transmit HART process variables and state variables; In addition to cyclic data exchange (used for reading and writing I/O data), it also supports Profibus extended diagnostic function, providing detailed information such as module and channel status to assist in high integrity operation and on-site maintenance of the system.

Configuration method

8502-BI-DP provides two main configuration methods to meet the setting requirements in different scenarios:

Configuration Method Tools/Dependency Core Features Applicable Scenarios

Parameterized configuration of Profibus configurator and GSD files is configured at the “module level”, and all channel configurations under a single module are consistent; Configuration is based on “logical modules” (corresponding to physical modules), and modules need to be added one by one and parameters selected in the configurator; Support HART “email” function, collect HART variables as needed, and save telegram data space; When the session starts, the configuration is sent from the Profibus host to the BIM. After the system restarts, the configuration will be retransmitted to pursue configuration efficiency, and the channel requirements within the module will be unified

The software configuration 8455-SW-CF configuration software and 8510-MO-NS node service module support “channel level” independent configuration, and each channel and alarm can be set separately; Configuration can be stored in BIM or saved to the 8510-MO-NS module for quick recovery during BIM replacement; Using independent GSD files, data frames are constructed based on “data blocks”, and the software automatically generates a telegram data mapping table for host programmers to identify data. It is necessary to flexibly set up a single channel or ensure that the configuration can be quickly restored in scenarios where data needs to be recognized

In addition, the address can be set through BIM software, the Profibus “Set Slave Address” command, or the switch settings of the 8510-NS-MO module; The 8510-NS-MO module also has automatic configuration function.

GENERAL DESCRIPTION

The VMIVME-3115 is a high throughput ,12-bit Analog Input/Output (AIO) board which provides four analog inputs, two analog outputs, and dual 8-bit bi-directional digital input/output ports for VMEbus system applications.  

Dual-ported data memory, on-board timers, and a program-controlled bus interrupter enables the VMIVME-3115 board to support extensive analog input and output traffic with minimum involvement of the host processor.

Sample-and-hold input amplifiers provide “snapshot” simultaneous sampling of all analog inputs at aggregate sample rates up to 2 MHz, and virtually eliminate time skewing between input channels.  The VMIVME-3115 supports both independent and multiboard synchronization.  Dual analog outputs enable the board to “close the loop” in system servo applications.  

Analog input data is stored sequentially in dual 256 Kbyte buffer memories.  The host controls which one of the two buffers will reside in VMEbus memory through a single toggle bit in the Control and Status Register (CSR).  The host can also direct the board to generate an interrupt when a scanning sequence is completed.

Analog inputs can be sequenced either continuously, single block synchronously, or multiboard synchronously.  In the continuous mode, sequencing executes

continuously until stopped by the host processor.  In the single block synchronous mode, a preselected block of data is transferred, after which VMIC • 12090 South Memorial Parkway • Huntsville, Alabama  35803-3308 sequencing halts.  Multiboard synchronization can be applied to either the continuous or single block modes, with a designated board controlling other VMIVME-3115 boards.  

Each buffer memory appears as 256 Kbytes of VMEbus memory.  To simplify automatic system configuring, the buffer is disabled during power up and reset operations.  To support multiple VMIVME-3115 boards without requiring additional memory space, the buffer can be removed from the VMEbus memory entirely through a control bit in the I/O space CSR.  The buffer  is jumper locatable on any 4 0000 byte (HEX) boundary in the VMEbus memory space.  Block Mode D16 data transfers (BLT) are supported.

Dual analog output channels can drive 10 mA loads over the maximum output range of ±10 V.  On-line or off-line (disconnected) operation is program controlled.  Each analog output is controlled directly by a single 16-bit word in the VMEbus short I/O space.

FUNCTIONAL CHARACTERISTICS

Sequence Initiation: Scanning can be programmed to commence either upon direct command from the host, or by an external TTL trigger event.  Scan rate for the analog inputs  is program controlled.

The external trigger line also can be used to synchronize multiple VMIVME-3115 boards for simultaneous sampling of large arrays of analog signals.  For multiboard sychronization, a specific VMIVME-3115 board is designated the synchronous master, while the remaining boards

are designated as slaves.  The master then controls the sequencing of all slave boards.

Digital I/O Ports: 16-bit parallel digital input and output capability is provided by dual 8-bit TTL

data ports.  Each port can be program configured as either an input or output port, and is accessible in the short I/O space in which the Control

Registers for the board are located.

I/O Addressing: Addressable as 16 contiguous 16-bit registers, located on any 16-word boundary

within the short supervisory or short nonprivileged I/O space.

Memory Addressing: The Analog-to-Digital Converter (ADC) buffer appears as conventional

memory to the VME host.  Total memory space occupied by the board is 256 Kbytes, and can be program located on any 4 0000 byte (HEX) boundary in the VMEbus memory space.  The

VMIVME-3115 buffers can be removed (masked) from VMEbus memory by a CSR control bit.

I/O Address Selection: Board address in the short I/O space is selected by on-board field

selectable jumpers.  Operation is supported in any slot except slot 1.

Access Privilege: Address modifiers are decoded to support either supervisory, nonprivileged, or both accesses.  Jumpers are provided to support this feature, and are factory configured for either access.  Decoded modifier codes include 09, 0A, 0B, 0D, 0E, 0F, 2D, 29, 39, 3A, 3B, 3D, 3E, and 3F.

VMEbus Interrupt: The VMIVME-3115 can be programmed to generate an IRQ1 to IRQ7 when

either buffer is full.  The interrupt response vector is controlled by an on-board Interrupt Vector Register.

Board Identification: The Board Identification Register (BIR) contains the VMIVME-3115 identification code.

Self check and diagnosis: After the system is reset, the self check program will automatically run, and the self check register can provide feedback on the results (success/failure) and fault channel information; The output can be disconnected from the on-site wiring to achieve offline self-test, while the onboard rich diagnostic testing functions are convenient for troubleshooting.

Front panel design: equipped with status LED indicator lights (lit after reset, turned off after successful self check and automatic calibration, can be controlled by software switch); Provide analog output connectors, reference voltage access interfaces (with isolated BNC connectors and adjustment functions), and external synchronous signal connectors for convenient operation and monitoring.

Description

The 1900/65A General Purpose Equipment Monitor is  designed to continuously monitor and protect equipment that is used in a variety of applications and industries.  The monitor’s low cost makes it an ideal solution for general purpose machines and processes that can benefit from continuous monitoring and protection.

Inputs

The 1900/65A provides four transducer inputs and four temperature inputs.  Software can configure each transducer input to support 2- and 3-wire accelerometers, velocity sensors or proximity sensors.  Each temperature input supports Type E, J, K, and T thermocouples, and 2- or 3-wire RTDs.

Outputs

The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output.  The user can use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert and

Danger statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output.  The dedicated buffer output can provide the signal for each transducer input.

A Modbus Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), or System 1 software.  The monitor uses an internal counter and a Modbus client/master time reference to generate time and date information.  Users can upgrade monitors without the Modbus Gateway by ordering the 1900/01 Communications Upgrade (see the Ordering Information section).  The 1900/65A supports Modbus communications via Ethernet and a software-configurable RS232/485 serial port.

Configuration

The user defines monitor operation and the Modbus Gateway register map by using

software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection.  The 1900/65A permanently stores configuration information in non-volatile memory, and can upload this information to the PC for changes.

Display Module

The 1900/65A supports an optional display/keypad to view channel information or

make minor configuration changes. This allows the 1900/65A to operate as a stand-alone package.  If desired, the user can mount the display up to 75 metres (250 feet) from the Monitor Module.

Core product features and technological highlights

1. Multi dimensional protection function (core value)

The 369 series relay focuses on “comprehensive protection” and covers common types of equipment failures in the power system, including:

Overcurrent protection: For overload and short circuit faults of equipment such as lines, transformers, motors, etc., multiple protection logics such as definite time and inverse time are provided to adapt to different load characteristics.

Grounding fault protection: supports residual current detection, quickly identifies single-phase grounding, three-phase unbalanced grounding and other faults, and avoids fault expansion (especially suitable for neutral point ungrounded or arc suppression coil grounded systems).

Special equipment protection: customized protection algorithms are provided for specific equipment such as transformers (such as over temperature and differential auxiliary protection), motors (such as locked rotor and phase loss protection), capacitors (such as overvoltage and undervoltage protection), etc.

Backup protection function: It can serve as a backup for the main protection and automatically activate when the main protection fails, ensuring the “multi-level protection” of the power system and improving power supply reliability.

2. Monitoring and data collection capabilities

Real time parameter monitoring: Continuously collect electrical parameters such as voltage, current, power, frequency, power factor, etc., with accuracy meeting industrial standards (such as current measurement accuracy ± 0.5%, voltage ± 0.2%), and supporting remote data reading.

Fault recording and event recording: When a fault occurs, automatically record the waveform of electrical parameters before and after the fault (the recording time can be configured) and the timing of events (such as switch action time, protection action logic), which facilitates post fault analysis and responsibility tracing.

Status diagnosis: Monitor the hardware status of the device (such as power supply and sampling module) and the operating trend of the protected equipment (such as motor winding temperature trend), and provide early warning of potential faults (such as module aging and equipment degradation).

3. Control and communication characteristics

Local/Remote Control: Supports local panel operations (such as manual opening and closing, protection setting modification) and remote control (remote control of switches and setting issuance through communication interfaces), suitable for the needs of “unmanned substations” or “remote operation and maintenance”.

Flexible communication interface: Ethernet (such as Modbus TCP, IEC 61850), serial port (RS-485/232, such as Modbus RTU) and other communication protocols are standard or optional, which can be connected to SCADA (Supervisory Control and Data Acquisition System), DCS (Distributed Control System) or power automation platforms to achieve data interconnection and intercommunication.

Fixed value management: supports multiple sets of protection fixed value storage and switching (such as “operation fixed value” and “maintenance fixed value”), adapts to different operating conditions (such as seasonal load changes and equipment maintenance modes), and the switching process does not require power outage.

4. Usability and reliability design

Human computer interaction: equipped with a small LCD display screen (supporting Chinese/English interface switching) and buttons, with intuitive operation; Some models support exporting data (such as fault recording files and operation logs) through the USB interface, simplifying on-site debugging.

Hardware reliability: Industrial grade components are used, with a protection level of IP30 (panel installation) or IP20 (cabinet installation), and a working temperature range covering -40 ° C to+70 ° C, suitable for harsh industrial environments such as high and low temperatures, humidity, electromagnetic interference, etc; Support redundant power input (optional) to avoid protection failure caused by single power failure.

Compliance: Complies with international and industry standards, such as IEC 60255 (General Standard for Relays), ANSI/IEEE C37.20.1 (Standard for Metal Enclosed Switchgear), GB/T 14598 (Chinese Relay Protection Equipment Standard), ensuring compliant use in different countries/regions.

Applicable application scenarios

The 369 series relays are widely used in various fields of medium and low voltage power systems due to their strong versatility and flexible adaptability, including:

Industrial power distribution systems, such as motor control centers (MCC), transformer cabinets, and capacitor compensation cabinets in factory workshops, protect critical production equipment from faults and reduce downtime losses.

Commercial and civil buildings, such as large shopping malls, office buildings, and data centers, use power distribution systems to ensure stable power supply for important loads such as air conditioning, lighting, and IT equipment, avoiding business interruptions caused by power outages.

Power distribution network: such as 10kV/0.4kV lines, ring main units, and box type substations in urban distribution networks, serving as line protection and monitoring nodes to enhance the reliability and operational efficiency of the distribution network.

Renewable energy access: Adapt to the grid connection protection of distributed photovoltaics and small-scale wind power, prevent the impact of new energy generation fluctuations on the power grid, and ensure grid connection safety (such as overvoltage and overclocking protection).

Customer Value and Service Support

1. Customer core revenue

Improving reliability: By using multi-level protection and rapid fault removal, the equipment damage rate is reduced and the duration of power outages is reduced (such as fault removal time ≤ 50ms, which is much faster than traditional relay protection).

Reduce operation and maintenance costs: remote monitoring and diagnostic functions reduce the frequency of on-site inspections; Fault recording and event recording simplify fault analysis and shorten fault handling time.

Flexible Expansion: Supports seamless integration with other power automation products from GE Grid Solutions, such as SCADA systems and distribution management platforms, to meet customers’ upgrade needs from single point protection to system intelligence.

2. Service and Support
