IS200TRLYS1B - TRLY Relay Output Terminal Board | GE Mark VIeS | B7B

IS200TRLYS1B is a General Electric TRLY Relay Output Terminal Board with Coil Sensing for GE SPEEDTRONIC™ Mark VIeS Safety control systems. The TRLY function supports relay output 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 holding 12 plug-in magnetic relays: the first six relay circuits are jumper-configurable for dry contact, Form-C contact, or solenoid-driving outputs from a 125 V dc, 115/230 V ac, or optional 24 V dc source; the next five relays are unpowered isolated Form-C contacts; the final output is an isolated Form-C contact used for special applications such as ignition transformers. This revision is documented as IEC 61508 safety-certified with the Mark VIeS YDOA I/O pack, across all versions. Connector JA1 is used for simplex applications, with JR1, JS1, and JT1 used for TMR applications.

This component is typically considered when troubleshooting Mark VIeS Safety 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.
