Description
🔹 Product Description
The GE IS200TBAIH1C, also identified as IS200TBAIH1CDC, is a TBAI Analog Input/Output Terminal Board designed for the GE Mark VI Speedtronic turbine control system. It provides field termination and signal conditioning for analog instrumentation and interfaces with the VAIC analog I/O board. The board supports 10 analog inputs and 2 analog outputs and can be configured for simplex or Triple Modular Redundant (TMR) applications.
The board uses two barrier-type terminal blocks with 24 terminals each and three DC-37 connectors for connections to the associated control hardware. Jumper settings allow configuration of input current/voltage modes and analog output ranges. The TBAI design also includes signal suppression and filtering functions for industrial analog signals.
