IS200TRLYH1BGG  Functional Description 

The Turbine Specific Primary Trip Board IS200TRLYH1BGG is a Triple Modular Redundant (TMR) Relay Output Terminal Board designed for GE's Mark VIe Series turbine control systems. This critical component provides 12 contact-voted relay outputs using 36 sealed relays (12 per R/S/T section) to ensure maximum reliability in power generation applications. The board supports 24/125V DC or 115V AC operation and features Form A (NO) voted contacts for fail-safe operation in Class 1 Division 2 hazardous environments.

With 16 channels of SPDT relays rated for 10A switching current, the IS200TRLYH1BGG Coil Sensing Terminal Board delivers robust performance. The TMR architecture requires signals from three I/O processors (R/S/T) through JR1/JS1/JT1 connectors, with each section having independent power supplies. For complete systems, the optional IS200WPDFH1A power distribution board can be added to provide fused 24V DC/115V AC/125V DC field power. The DIN rail-mountable design accepts #12 AWG wires via two terminal blocks with shield grounding strips.

The GE Proximitor Monitor IS200TRLYH1BGG operates on 28V DC logic power from connected I/O processors, with a failsafe design that de-energizes relays upon communication loss.The General Electric IS200TRLYH1BGG Relay Output Terminal Board TMR contact voting circuit combines R/S/T relay outputs into a single high-integrity signal, while the Form A (NO) configuration ensures safe-state shutdowns. A companion TRLY2F variant provides Form B (NC) outputs for different application requirements. Both versions meet stringent demands for gas/steam turbine protection systems.

As part of GE's legacy turbine controls, the IS200TRLYH1BGG GE Control System is available for repair/replacement through certified suppliers. Specialists offer OEM replacements, board repairs, and warranty-backed rebuilt units to maintain system uptime. For integration, ensure proper wiring to terminal blocks and consider adding WPDF boards for power distribution. The board's -40°C to +85°C operating range and vibration-resistant design guarantee long-term reliability in harsh power plant environments.
