Model system and core specifications
（1） Model classification logic
This series of terminal blocks is divided into two core series based on redundancy design. Each series is subdivided into specific models according to application types. The suffix code for all models is fixed at -0, with no other optional configurations. The classification logic is clear, making it easy for users to quickly select according to their actual needs
Single series: The model suffix is “S”, suitable for conventional industrial scenarios without redundancy requirements, with a simple structure and controllable cost
Dual Redundancy Series: The model suffix is “D” and is suitable for critical industrial scenarios that require extremely high system stability and reliability (such as core control links in industries such as chemical, power, and petroleum). The dual redundancy design ensures signal continuity in the event of a failure

（3） Summary of Key Characteristics of Specifications
Channel number pattern:
8-channel models: a total of 8 types (4 single channel+4 dual redundant), covering analog input/output RTD/POT、 Four major categories of applications for digital output, meeting most conventional signal transmission needs
16 channel models: 4 types in total (2 single channel+2 dual redundant), only suitable for thermocouple/mV and digital input applications, suitable for scenarios requiring high-density signal acquisition, reducing the number of terminal block installations
Reason for weight difference: The single channel series is uniformly 0.2kg, and the dual redundancy series is uniformly 0.3kg. The weight increase is due to the additional hardware components such as circuits and wiring terminals required for the dual redundancy design, ensuring the implementation of redundancy functions
Module adaptation uniqueness: Each terminal block model corresponds to only one specific I/O module and cannot be mixed across models to avoid signal transmission failures or equipment damage caused by module and terminal block incompatibility
External dimensions and installation compatibility
（1） Size specification classification
The size of the terminal block is directly related to the redundancy design, and all models within the same series have identical dimensions for standardized installation layout. The specific specifications are as follows:
Series types include model size parameters (unit: mm), reference drawings, installation and adaptation scenarios
Single channel series ATSA3S, ATSS3S, ATST4S, ATSR3S, ATSB4S, ATSD3S length x width x height: 32.6 x 60.5 x 114 F02E.ai is suitable for control cabinet layouts with limited installation space and no need for redundant design, and can be densely arranged
The dual redundant series ATSA3D, ATSS3D, ATST4D, ATSR3D, ATSB4D, ATSD3D length x width x height: 65.6 x 72 x 114 F05E.ai is suitable for the layout of control cabinets in critical control areas and requires a certain amount of installation space to ensure the heat dissipation and maintenance convenience of redundant components
（2） Dimensional design features
Height uniformity: All models have a height of 114mm, which facilitates the planning of installation positions according to the floor height inside the standard control cabinet and improves the cleanliness of the installation layout
Width differentiation: The width of the dual redundant series (72mm) is greater than that of the single channel series (60.5mm), and the length (65.6mm) is greater than that of the single channel series (32.6mm), adapting to the spatial requirements of its internal redundant structure
Standardized design: The dimensions comply with industrial equipment installation specifications and can seamlessly adapt to other supporting equipment of the Yokogawa CENTUM VP system (such as I/O modules, control cabinet rails, etc.), reducing installation difficulty
Model coding rules and ordering requirements
（1） Detailed explanation of coding rules
Explanation of optional/fixed values for the meaning of coding components
The prefix (such as ATSA, ATSS, etc.) application type identification ATSA (analog input), ATSS (analog output), ATST (thermocouple/mV), ATSR (RTD/PAT), ATSB (digital input), ATSD (digital output) prefix directly corresponds to the core application functions of the terminal block, making it easy to quickly identify
Intermediate numbers (such as 3S, 3D, 4S, 4D, etc.) indicate the number of channels and redundancy types. 3S (8 channels+single channel), 3D (8 channels+double redundancy), 4S (16 channels+single channel), 4D (16 channels+double redundancy) numbers “3” correspond to 8 channels, and “4” corresponds to 16 channels; The letters “S” and “D” distinguish redundant types
Suffix code configuration identifier -0 (fixed value) All models use a unified suffix code, with no additional optional configurations, simplifying the selection and ordering process
（2） Ordering requirements
Users need to specify the complete model (including suffix code) when placing an order, for example:
Conventional simulation input scenario: Order “ATSA3S-0”
Key scenario digital output: Order “ATSD3D-0”
Due to the fixed suffix code of -0, the core needs to confirm the model body composed of the prefix and the middle digit to ensure a complete match with the actual application type, channel number, and redundancy requirements.

Advantages: Reduce on-site wiring costs, simplify construction difficulties, and adapt to large-scale industrial scenarios.
Key selection and deployment considerations
1. Key selection points
Confirm the communication interface (RS-232/RS-422/RS-485) and Modbus mode (RTU mode required) of the device;
Determine whether the module capacity meets the requirements based on the number of devices (≤ 64) and data points (≤ 2000 DCI connections);
In hazardous environments, it is necessary to confirm the installation area level (Class I, Division 2 or Zone 2) to ensure that the module matches the certification of the TA;
When the communication distance exceeds 15m (RS-232) or requires multi-point connection, RS-485 interface is preferred.
2. Deployment precautions
Wiring specification: RS-422/RS-485 requires shielded twisted pair cables, and terminal resistors (configured through TA’s DIP switch) should be enabled at both ends of the bus to avoid signal reflection; RS-232 wiring needs to match the device pin definition (adjusted through TA’s DIP switch);
Power configuration: It is recommended to use redundant power supply in key scenarios to avoid module shutdown caused by power failure;
Electromagnetic interference protection: Modules and cables should be kept away from strong electromagnetic interference sources such as frequency converters and motors, and the shielding layer should be grounded at one end to reduce interference effects;
Software compatibility: Ensure that the control system software version meets the requirements (I/A Series v8.8+or Foxboro Evo v9.0+) to avoid incompatibility between configuration tools and the system.
The Compact 200 Series I/O subsystem is a distributed control electronic device designed for industrial sites.
