IS200DTTCH1A - DTTC Thermocouple Board | GE Mark VIe | B7B

IS200DTTCH1A is a General Electric DTTC Thermocouple Board for GE SPEEDTRONIC™ Mark VIe control systems. The DTTC function supports temperature input 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.

DTTC is a DIN-rail-mounted thermocouple input terminal board in the Mark VIe thermocouple I/O family, which also includes the STTC and TBTC terminal board styles. GE documentation notes that the PTCC I/O pack is compatible with the TBTC and STTC terminal boards, but not with the DIN-rail-mounted DTTC board; the compatible I/O pack for this terminal board form should be confirmed against site documentation. The component is supplied as a Board/PWA hardware assembly.

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.
