The IS200TRLYH1B is a high-reliability Relay Output Terminal Board (TRLY) designed for the GE Speedtronic Mark VI turbine control system. This terminal board serves as the physical interface between the Mark VI control system and external field devices. It is equipped with an array of high-quality mechanical relays that convert low-voltage digital signals from the control processor into high-current outputs, allowing the system to operate critical plant components such as solenoids, contactors, alarm horns, and valve actuators.
