IS200TRPGS1B - TRPG Primary Trip Gas Terminal Board | GE Mark VIeS | B7B

IS200TRPGS1B is a General Electric TRPG Primary Trip Gas Terminal Board for GE SPEEDTRONIC™ Mark VIeS Safety control systems. The TRPG function supports primary gas turbine trip protection operation in turbine control and balance-of-plant applications that use the Mark VIeS 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.

GE documentation identifies this revision as providing 3 monitored trip relay outputs when used with the YTURS1A I/O pack. TRPG is documented as working as a board pair with TREG, with power for trip solenoids entering through the TRPG J1 connector. TRPG is also documented as mounting below the PSFD Flame Detector Power Supply, which connects to J3, J4, and J5 on TRPG in a diode-ORed, TMR configuration rated at 335 V dc / 5 mA to power up to eight flame detectors. The hardware uses a box-style terminal block. It should be matched with the compatible TREG terminal board where that pairing is used in the site configuration.

This component is typically considered when troubleshooting Mark VIeS Safety hardware, replacing a failed module, evaluating repair options, or maintaining spare inventory for turbine protection 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.
