FUNCTIONAL DESCRIPTION:
IS220STTCH2A is a Simplex Thermocouple Compact Terminal Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Control Systems. The STTC terminal board is a compact one designed for DIN-rail or flat mounting. The board has 12 thermocouple inputs and connects to either the PTCC thermocouple processor board on the Mark VIe or VTCC thermocouple processor board on the Mark VI. The onboard signal conditioning and cold junction reference are identical to those on the larger TBTC board. High-density Euro-Block type terminal blocks are mounted to the board, and two types are available. An on-board ID chip identifies the board to the processor for system diagnostic purposes. In the Mark VIe systems, the PTCC I/O pack works with the STTC. The I/O pack plugs into the DC-37 pin connector and communicates with the controller over Ethernet. Only simplex systems are supported.
INSTALLATION:
The STTC and a plastic insulator mount on a sheet metal carrier, which mounts on a DIN rail. The STTC and insulator mount on a sheet metal assembly that bolts directly in a panel. Thermocouples are wired directly to the terminal block using typical #18 AWG wires. The Euro-Block type terminal block has 42 terminals that can be fixed or removable. Two types of Euro-Block terminal blocks are available as follows:
OPERATION:
The connection of the STTC to the I/O pack or board that contains the A/D converter is shown in the following figure. The I/O pack or board excites the cold junction (CJ) reference on the terminal board. The 12 thermocouple signals plus the CJ signal and the connection to the identity chip (ID) come through connector JA1.

What is a Simplex Thermocouple Compact Terminal Board?
A Simplex Thermocouple Compact Terminal Board is a device used in industrial control systems for connecting thermocouples to the control system. It provides a streamlined and compact interface for measuring temperature signals from thermocouples.
What types of thermocouples are compatible with the terminal board?
Most compact terminal boards are compatible with standard thermocouple types such as Type J, K, T, and E, but compatibility depends on the specific model of the board.
How does cold junction compensation (CJC) work in the terminal board?
Cold junction compensation accounts for the temperature at the connection point of the thermocouple and the terminal. It ensures the accuracy of the thermocouple readings by adjusting for any discrepancies between the reference junction and the actual ambient temperature.
