The GE IS200TRLYH1BED is a Relay Output Terminal Board designed for GE Mark VI and Mark VIe turbine control systems. It provides an interface between the turbine control system and external electrical devices through relay-based output circuits.
The board receives control commands and uses electromagnetic relays to operate external equipment. Typical controlled devices include solenoid valves, alarms, auxiliary circuits, and other field actuators. Its design supports reliable switching and helps maintain stable communication between control hardware and field equipment.
