IS200TRLYH2E - TRLY Relay Output Terminal Board | GE Mark VIe | B7B

IS200TRLYH2E is a General Electric TRLY Solid-State Relay Output Terminal Board 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 a 12-output board using solid-state relays for the outputs, with isolated output voltage feedback on all 12 circuits; unlike mechanical relay boards, all 12 outputs are single, normally-open contacts with no on-board solenoid power distribution. TRLYH2E is documented as the 24 V dc application version of this board family (compared with TRLYH1E for 115 V ac and TRLYH3E for 125 V dc applications). The hardware uses a terminal block accepting up to #12 AWG wire, with connector JA1 used for simplex applications and connectors JR1, JS1, and JT1 used for TMR applications. 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.
