Core functions and application positioning

1. Core protection and control functions

Multiple fault protection: As a low-voltage distribution protection component, the core function of the 31H7 series is to monitor the current of the distribution circuit, trigger protection actions for faults such as overload (continuous current exceeding the set value), short circuit (instantaneous surge of current), etc. (such as cutting off the circuit, disconnecting the load), avoid overheating of the circuit, equipment burnout, and reduce the risk of electrical fires.

Overload protection: with adjustable action threshold and delay characteristics, suitable for different power distribution circuits (such as lighting circuits, small motor circuits), can avoid triggering protection by starting surge current.

Short circuit protection: adopting instantaneous action design (millisecond level response), quickly cutting off the fault circuit, limiting the impact of short-circuit current on the distribution system, and protecting upstream circuit breakers and distribution equipment.

Circuit control assistance: Some models may integrate manual opening and closing functions, support on-site start stop control of the distribution circuit, and have status indicators (such as LED lights displaying circuit on/off/fault status), making it easy for operation and maintenance personnel to quickly identify the circuit status.

2. Typical application scenarios

Based on the document association of “PSS (Power System Solutions)” and “NWEQUIP” identification, the 31H7 series is mainly suitable for the following scenarios:

Commercial building power distribution: such as lighting circuits in office buildings and shopping malls, and power distribution protection for air conditioning terminal equipment (fans, coils);

Industrial auxiliary power distribution: protection of auxiliary circuits in factory workshops (such as control power supply and small instrument power supply circuits);

The FBM237 contains eight 0-20 mA analog output channels. In situations where control system reliability is important, the FBM237 may have a redundant module installed. This permits all eight outputs to maintain operation in the presence of a single fault and during the time that the suspect module is removed and replaced. The 0-20 mA signals are electrically compatible with HART ®  field devices.

Module core functions and features

FBM237 is an 8-channel galvanized isolated 0~20mA analog output module. Its core design revolves around high reliability, flexibility, and compatibility. The key functions and features are as follows:

（1） Core functions

Multi scenario output capability:

Output range: 0~20.4mA DC (out of range design, compatible with standard 0~20mA actuators), single channel maximum load of 750 Ω, meeting the driving requirements of most industrial field equipment;

HART compatibility: The channel impedance meets the requirements of HART high impedance devices, can be connected to a HART handheld communicator (HHC), does not interfere with HART signal transmission, and supports intelligent device debugging and diagnosis.

Redundant deployment and failover:

Redundancy mode: Two FBM237s form a redundant pair and need to be installed in adjacent odd/even positions on the base (such as 1&2, 3&4), in conjunction with the redundant adapter RH916QD to achieve signal sharing;

Fault handling: Synchronize output commands through the AOUTR function block of Foxboro Evo control software. When a single module fails, automatically drive the fault channel current to 0mA. Normal modules seamlessly take over, and replacing faulty modules does not interrupt on-site output.

Safety and protection design:

Channel isolation: Each channel is Galvanically isolated from other channels and ground, withstanding 600V AC (1 minute) to avoid interference between channels and ground faults;

Current limit: The maximum output current of a single channel is about 25mA to prevent overload damage to the actuator;

Fail Safe: Supports “Hold” or “Fallback” modes, with a configurable fallback value of 0mA to avoid the risk of “high output failure”.

（2） Key characteristics

Environmental adaptability: Complies with ISA S71.04 G3 level harsh environmental standards, can withstand vibration (0.75g @ 5-500Hz), wide temperature range (working -20~70 ℃, storage -40~70 ℃), and is suitable for industrial high temperature and high dust scenes;

Hot plugging and maintenance: Module replacement does not require dismantling of on-site wiring, power or communication cables, and redundant module maintenance does not affect the operation of on-site equipment; Partial termination components (TA) with bypass sockets, supporting temporary output maintenance through bypass stations (such as P0900HJ);

Status indication: The front LED light provides real-time feedback on the communication status, power status, and channel faults of the module, making it easy to quickly locate problems;

Communication reliability: Connected to the fieldbus communication module (FCM) or control processor (FCP) through a 2 Mbps redundant fieldbus, supporting A/B dual path switching, and ensuring uninterrupted data transmission in case of single path failure.

Installation and Termination Component (TA) Configuration

FBM237 needs to be used in conjunction with a dedicated base, termination assembly (TA), and cables. Installation and wiring must follow strict specifications, with the following core requirements:

（1） Base and installation

Base type:

Modular base: Supports DIN rail (32mm/35mm) or 19 inch rack installation, with a maximum capacity of 8 FBM modules per base;

Redundant installation: Redundant modules need to be fixed in adjacent odd/even positions, connected to the base terminals through the redundant adapter RH916QD, to achieve two modules sharing one TA signal interface.

Installation specifications:

Heat dissipation space: Reserve ≥ 25mm space on each side of the module to avoid the influence of adjacent devices on heat dissipation;

Grounding requirements: Galvanized yellow chromium steel DIN rails are preferred for the base to ensure reliable grounding, and aluminum/plastic rails are prohibited (which may cause poor grounding).

（2） Termination Component (TA) Selection

TA is a key component connecting FBM237 with on-site actuators, providing signal switching and bypass maintenance functions. It needs to be selected according to the scenario, and the specific model and adaptation scenario are as follows:

TA model core function adaptation scenario authentication type

RH916YE (main TA) 8-channel signal transfer, no bypass function, normal scenario (no online maintenance required) Type 1/2 (compatible with hazardous areas)

Dangerous area operation:

Shell requirements: It must be installed in a certified shell with a protection level of IP54 or above, and the shell must be opened with tools to prevent unauthorized operation;

Maintenance process: Power off or confirm that the area is in a non hazardous environment before connecting/disconnecting cables. Redundant module replacement should be carried out after the faulty module is powered off.

Upgrade and compatibility instructions

FBM237 is mainly used to replace the Foxboro 100 series FBM37 analog output module. When upgrading, the following compatibility points should be noted:

Hardware replacement: A single FBM237 can directly replace one FBM37, and on-site wiring can be reused in two ways:

Direct adaptation: Use the documentation to specify the TA (such as RH916YE) and rewire it to the TA terminal;

Adapter reuse: Connect the terminated component adapter (TAA, refer to PSS 31H-2W4) directly to the original FBM37 wiring without rewiring.

Software adaptation:

Should be paired with Foxboro Evo control software v8. x+or Control Core Services v9.0+, supporting AOUTR redundant function block configuration;

The failure safety parameters need to be pre-set in the software (such as a fallback current of 0mA and a fault delay time) to ensure that the actuator is in a safe state in case of a fault.

Core functions and features of the module

FBM217 is a 32 channel discrete input module designed specifically for industrial environments, supporting multi voltage level signal acquisition and high reliability operation. Its core functions and features are as follows:

High voltage: 240V AC (logic 0:0~40V AC, logic 1:164~264V AC).

Redundancy deployment capability: Supports single module or redundant paired deployment (2 FBM217s need to be installed in adjacent odd/even positions on the base, with the redundant adapter RH926ZY). In redundancy mode, the input signal quality is verified through the CINR function block of Foxboro Evo control software, and the optimal signal is automatically selected.

Event Sequence (SOE) Function: In conjunction with I/A Series v8. x and above software or Control Core Services v9.0+, supports event collection, storage, and reporting, with optional GPS time synchronization (accuracy up to 1ms); The old version software (before v8. x) needs to be implemented through the ECB6/EVENT block, with an accuracy of 1 second and no cross processor synchronization.

Signal conditioning and protection: relying on termination components (TAs) to achieve optical isolation, current limitation, and voltage attenuation. Some TAs support external excitation power supply access without the need for additional on-site circuit protection equipment (such as fuses).

Installation and Termination Component (TA) Configuration

FBM217 needs to be used in conjunction with a dedicated base and termination assembly (TA), and installation and wiring must follow strict specifications. The core requirements are as follows:

（1） Base and installation

Base type: Modular base (DIN rail or 19 inch rack mounted), with a maximum capacity of 4 or 8 FBM modules per base;

Redundant modules need to be installed in adjacent odd/even positions (such as 1&2, 3&4) and connected through redundant adapter RH926ZY;

Support 100 series conversion installation structure (refer to PSS 31H-2W8) for easy upgrading of old systems.

Installation specifications:

DIN rail: Supports 32mm/35mm specifications, with priority given to galvanized yellow chromium steel material (ensuring good grounding), fixed at a spacing of approximately 200mm;

Panel installation: Use M4 or # 8 screws and reserve heat dissipation space (≥ 25mm on each side of the module).

（2） Termination Component (TA) Selection

TA is the core component connecting FBM217 with on-site signals, providing signal conditioning, isolation, and power distribution functions. It needs to be selected according to the input signal type. Common TA and adaptation scenarios are as follows:

TA model adaptation signal type isolation level certification type

RH916CA (main TA) 30V DC voltage monitoring, 32 channel group isolation Type 1/2/4

RH916XZ (main TA) 24V DC contact detection, 32 channel group isolation Type 1/2/4

RH916YA (main TA) 132V AC/150V DC voltage monitoring, 32 channel isolation Type 1/4

RH916PU (main TA) 240V AC voltage monitoring, 32 channel isolation Type 1

RH924HB (Extended TA) replaces FBM12A/B expansion module, 16 channel group isolation Type 1/2/4

RH924HD (Extended TA) replaces FBM13 expansion module, 16 channel isolation Type 1/4

TA connection: The main TA is connected to the base through a Type 4 cable (37 pin D-sub interface), and the extended TA is cascaded through a Type 6 cable (main TA 25 pin → extended TA 37 pin), with a maximum cable length of 30m, supporting P/PVC or LSZH materials (LSZH is suitable for low smoke and halogen-free scenarios);

Upgrade adaptation: When replacing the 100 series FBM (such as FBM07A/B, FBM08, FBM20), it is necessary to match the corresponding main TA+extended TA (such as replacing FBM07A with RH924HA main TA+RH924HB extended TA).

Compliance certification and security requirements

（1） Core certification

The FBM217 module and its supporting TA comply with global safety and electromagnetic compatibility standards in multiple regions, with the following core certifications:

Specific standards and levels for certification categories

Low voltage safety EU Low Voltage Directive 2014/35/EU, in compliance with EN 61131-2 standard; UL Class 2 Circuit (Communication Circuit)

Environmental compliance complies with the EU RoHS 2011/65/EU directive, restricting the use of hazardous substances

Ship certification ABS type approval, French Classification Society (BV) EC31 environmental category certification

（2） Safety operation requirements

Electrical safety:

On site wiring must comply with Class 2 circuit restrictions (60V DC/30V AC, below 100VA), and high voltage TA must avoid long-term overvoltage operation (such as prohibiting the connection of signals above 300V AC to 240V AC modules);

Grounding requirements: The base is grounded through a DIN rail, and the use of aluminum/plastic rails is prohibited (which may cause poor grounding). The TA isolation channel needs to be grounded separately.

Dangerous area operation:

It needs to be installed in a certified enclosure with a protection level of IP54 or higher, and the enclosure needs to be opened with tools;

Before connecting/disconnecting cables, power off or confirm that the area is in a non hazardous environment. Replacement of non certified components is prohibited.

Upgrade and compatibility instructions

FBM217 is mainly used to replace Foxboro 100 series discrete input FBM modules. When upgrading, the following compatibility points should be noted:

Hardware replacement: A single FBM217 can replace one 100 series main FBM (such as FBM07A/B, FBM08)+one extended FBM (such as FBM12, FBM13), which needs to be matched with the corresponding functional main TA and extended TA (refer to the document “TA Selection Table for Migration”);

Software adaptation:

New system: requires Studio 5000 or Foxboro Evo control software v8. x+, supporting redundant CINR blocks and GPS SOE synchronization;

Old system: 100 series upgrade can use termination component adapter (TAA, refer to PSS 31H-2W4) without rewiring;

Cable Reuse: Some 100 series on-site cables can be adapted to FBM217 through TAA, but the voltage level and TA compatibility need to be confirmed.
