GE IS200TRPGH1BCC Termination Relay Board for Mark VI Turbine

The GE IS200TRPGH1BCC is a Termination Relay Board, integral to GE’s Mark VI turbine control systems, designed to complement the TREG board in managing emergency trip solenoids. It supplies the negative side of DC power to up to three trip solenoids, working in tandem with TREG (which provides positive power) to ensure balanced electrical supply for reliable emergency shutdowns.

Featuring robust terminal blocks for secure wiring, it connects to turbine control components via standardized connectors, supporting both simplex and TMR configurations. The board includes protective components like metal oxide varistors (MOVs) to suppress voltage spikes, enhancing durability in harsh industrial environments.

Controlled by the I/O processor, it integrates seamlessly with the system’s safety logic, ensuring rapid response during critical events. Its compact design fits into control cabinets, with components like relays and capacitors optimized for consistent performance. Ideal for gas, steam, and wind turbines, it reinforces system reliability in emergency trip mechanisms.
