IS210TRPGH1B - TRPG Primary Turbine Protection Terminal Board | GE Mark VIe | B7B

IS210TRPGH1B is a General Electric TRPG Primary Turbine Protection Terminal Board for GE SPEEDTRONIC™ Mark VIe control systems. The TRPG function supports turbine protection operation in turbine control and balance-of-plant applications that use the Mark VIe Terminal Board and I/O Hardware. It should be matched to the installed catalog number, hardware form, and cabinet configuration before it is used as a replacement.

TRPG is a primary turbine protection terminal board that works as a board pair with TREG: power for trip solenoids enters TRPG through its J1 connector and is then conducted to TREG over a J2 cable. When used with a JPDF power distribution board, the dedicated J7 output (a diode-OR of three fused, switched branch circuits) powers TRPG J1 so trip solenoid power comes from three parallel fused paths. The board should be matched with the compatible PTUR/YTUR primary protection I/O pack family used at the installed site.

This component is typically considered when troubleshooting Mark VIe hardware, replacing a failed module, evaluating repair options, or maintaining spare inventory for turbine control systems. Before installation, verify the catalog number, hardware revision, and associated terminal board or I/O pack configuration against site documentation and OEM requirements. The OEM reference for this listing is GEH-6721 Vol I; GEH-6721 Vol II.
