Description
1. Product Title
GE IS200VTCCH1CBB – Thermocouple Processor Board
2. Product Overview
The GE IS200VTCCH1CBB is a thermocouple input processor board from GE’s Mark VI turbine control system series. It accepts up to 24 thermocouple signals of types E, J, K, S, or T, performing cold junction compensation, linearization, and A/D conversion for precise temperature monitoring. This board addresses measurement accuracy challenges in turbine exhaust and metal temperature applications by filtering noise and providing high-resolution data to controllers. Paired with TBTC or DTTC terminal boards, the GE IS200VTCCH1CBB supports simplex and TMR redundancy, ensuring reliable thermal protection in gas and steam turbine environments.
