IS200STTCH2A - STTC Thermocouple Terminal Board | GE Mark VIe | B7B

IS200STTCH2A is a General Electric STTC Thermocouple Terminal Board for GE SPEEDTRONIC™ Mark VIe control systems. The STTC 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.

GE documentation identifies the supported point or channel information as 12 thermocouple inputs. The electrical or signal interface is documented as Thermocouple input interface. The hardware uses a S-type Euro-style terminal board form factor. The system architecture should be matched to the documented configuration, including Simplex per PTCC/YTCC listing. It should be matched with compatible hardware such as PTCC or YTCC 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.
