Description
🔹 Product Description
The GE IS200STTCH2A, also identified as IS200STTCH2ABA, is a Simplex Thermocouple Terminal Board designed for GE Mark VI turbine control systems. The STTC board provides field termination and signal conditioning for thermocouple inputs and incorporates cold-junction reference functions for temperature measurement. It is designed for DIN-rail installation and connects to the associated thermocouple processor or I/O hardware through its system interface. The board is suitable for turbine temperature monitoring applications where multiple thermocouple signals must be collected and transferred to the control system.
