1. Core Overview

• Model Interpretation: IS200TRLYH1BED (or IS200TRLYH1B) is the standard model of this series. It is usually used with IS200TRLYH1C, IS200TRLYH1D, etc., for different control levels.
• System Belonging: It belongs to GE Fanuc’s Mark VI control platform and is a key accessory for turbine and generator set control systems.
• Main Functions: It provides relay output and circuit termination functions, responsible for receiving instructions from the main control system (such as IS200DSPXH2 DSP module) and controlling actuators such as solenoid valves and switching valves.
