The IS200TRLYH1B module is a crucial component of the GE Mark VI turbine control system, specifically designed to provide reliable relay output functions.
It features 12 plug-in magnetic relays on the Relay Output with Coil Sensing (TRLY1B) terminal board.
These relays can be configured to drive external solenoids or dry, Form-C contact outputs, making them versatile for various control applications within the turbine system.
