IS200TREGS1B - TREG Emergency Trip Gas Terminal Board | GE Mark VIeS | B7B

IS200TREGS1B is a General Electric TREG Emergency Trip Gas Terminal Board for GE SPEEDTRONIC™ Mark VIeS Safety control systems. The TREG function supports emergency 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 YPROS1A I/O pack. TREG is documented as working as a board pair with TRPG: power for trip solenoids passes into TRPG through its J1 connector, then is conducted to TREG over a J2 cable. TREG also includes a JH1 power input connector that supplies contact wetting voltage to up to seven optional trip interlock contacts. The hardware uses a box-style terminal block. It should be matched with the compatible TRPG 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.
