Description
1. Product Title
GE IS200TRLYH1BGF – Terminal Relay Output Board
2. Product Overview
The GE IS200TRLYH1BGF is a relay output terminal board for GE Mark VI turbine control systems. It provides 12 independent relay outputs for switching high-power loads like solenoids, contactors, and ignition transformers based on commands from VCCC, VCRC, or VGEN processor boards. This board solves actuation challenges in turbine sequencing and protection by offering configurable dry/wet contacts with onboard suppression, ensuring reliable operation in simplex or TMR configurations. The GE IS200TRLYH1BGF connects via molded cables to VME racks, delivering precise control signals essential for startup/shutdown logic and emergency functions in power generation.
