IS200TRLYH1F - TRLY Relay Output Terminal Board | GE Mark VIe | B7B

IS200TRLYH1F is a General Electric TRLY 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 the supported point or channel information as 36 mechanical relays; 12 voted Form A normally open outputs. The electrical or signal interface is documented as 115 Vac, 24/48/125 V dc relay output circuits. The hardware uses a T-type barrier terminal board form factor. The system architecture should be matched to the documented configuration, including TMR only for TRLY_1F/2F. It should be matched with compatible hardware such as PDOA I/O pack; WPDF option board where applicable 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.
