Functional Description
IS200STTCH2ABA is a Simplex Thermocouple Board developed by GE. It is a part of Mark VIe control system. The terminal board is a versatile and compact solution engineered for efficient thermal monitoring and control. The board is equipped with 12 thermocouple inputs, providing ample capacity for monitoring multiple temperature points within a system.
Features
- Compatibility: It is designed to interface seamlessly with either the PTCC thermocouple processor board on the Mark VIe or the VTCC thermocouple processor board on the Mark VI. This compatibility ensures smooth integration with existing systems and enhances operational flexibility.
- Signal Conditioning and Cold Junction Reference: The STTC terminal board incorporates on-board signal conditioning and a cold junction reference, mirroring the functionality found on the larger TBTC board. This ensures accurate temperature readings by compensating for variations at the junction where the thermocouples connect to the board.
- Terminal Blocks: The board features high-density Euro-Block type terminal blocks. These terminal blocks are robust and designed for high-density wiring configurations, facilitating secure and reliable connections. Two different types of these terminal blocks are available to meet specific application requirements.
- Identification Chip: An on-board ID chip is included, which identifies the board to the processor. This feature plays a crucial role in system diagnostics, allowing for easier troubleshooting and maintenance by providing essential identification information to the processor.
Installation
- Carrier Assembly: The terminal board, along with a plastic insulator, is first mounted on a sheet metal carrier. This carrier provides the necessary support and stability for the terminal board.
- DIN Rail Attachment: The carrier assembly is then mounted onto a standard DIN rail. The DIN rail mounting system allows for easy installation and removal, as well as secure attachment within electrical panels or control cabinets.
- Panel Mounting: The terminal board and the plastic insulator can also be mounted on a sheet metal assembly. This assembly is designed to bolt directly into a panel, offering an alternative mounting option for installations where DIN rail mounting is not feasible or preferred. The sheet metal assembly is securely bolted into the panel, ensuring that the terminal board remains firmly in place during operation.
- Thermocouple Wiring: Thermocouples are wired directly to the terminal block of the board. This direct connection ensures minimal signal loss and maintains the integrity of the temperature readings.
- Wire Specifications: Typical 18 AWG wires are used for wiring the thermocouples to the terminal block. This wire gauge is commonly used for thermocouple connections due to its balance of flexibility and durability.
- Euro-Block Terminal Block: Terminal Specifications: The Euro-Block type terminal block on the board has a total of 42 terminals, providing ample connection points for multiple thermocouples and associated wiring. Fixed or Removable Options: The terminal block comes in two configurations - fixed or removable. The fixed terminal block offers a more permanent and secure connection, while the removable version allows for easier maintenance and replacement of wires without disturbing the entire setup.
Operation
- The operation of the terminal board involves a precise connection setup to ensure accurate temperature measurement and reliable system performance. The board connects to the I/O pack or board that houses the analog-to-digital (A/D) converter. This connection is critical for the board's functionality, enabling the transfer of thermocouple signals and system diagnostics.
- The I/O pack or board plays a vital role in providing the necessary excitation for the cold junction (CJ) reference on the board. The CJ reference is essential for compensating the thermocouple readings, ensuring accurate temperature measurements by accounting for the varying ambient temperatures at the connection point.
- The terminal board processes a total of 12 thermocouple signals. These signals, along with the CJ reference signal and the connection to the identity chip (ID), are routed through a specific connector, designated as JA1. This connector ensures a streamlined and organized connection, facilitating efficient data transmission and system integration.
- By following this connection setup, the terminal board can effectively interface with the I/O pack or board, ensuring precise temperature monitoring and reliable operation within the system.
