📦 Product Introduction
The GE Fanuc IS200EPCTG1A is an I/O terminal/interface board in the the IS200 family used within the Mark VI / Speedtronic turbine control / power generation control systems. It acts as a terminal board or interface circuit board that interfaces signals (analog, digital, etc.) between field devices, sensors, transformers (PT/CT circuits) or auxiliary systems and the internal control modules of the Mark VI system.
This board ensures proper signal routing, isolation, terminal connections, and may include some protective and conditioning circuitry (e.g. surge suppression, filtering). It is intended for use in harsh industrial environments, typically in power plants, turbines, and large process industries.
It integrates seamlessly with other IS200 modules to build a complete control rack or bay in turbine control systems.
