IS200TRLYH1D - TRLY Relay Output Terminal Board | GE Mark VIe | B7B

IS200TRLYH1D is a General Electric TRLY Relay Output Terminal Board with Solenoid Integrity Sensing for GE SPEEDTRONIC™ Mark VIe control systems. The TRLY function supports relay output 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.

GE documentation identifies this revision as holding six plug-in magnetic relays configured as Form-C contact outputs, powered and fused to drive external solenoids from a 24 V dc or 125 V dc source. The board provides feedback on each relay circuit, sensed between the NO output terminal and the SOL output terminal, to detect a failed external solenoid. The hardware uses a terminal block accepting up to #12 AWG wire, with connector JA1 used for simplex I/O packs and connectors JR1, JS1, and JT1 used for TMR I/O packs. It should be matched with the compatible PDOA I/O pack where that pairing is used in the site configuration.

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.
