IS220PTCCH1B - PTCC Thermocouple I/O Pack | GE Mark VIe | B7B

IS220PTCCH1B is a General Electric PTCC Thermocouple I/O Pack for GE SPEEDTRONIC™ Mark VIe control systems. The PTCC function supports temperature input operation in turbine control and balance-of-plant applications that use the Mark VIe / Mark VIeS Distributed Control 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 with STTC/TBTC family boards. The electrical or signal interface is documented as Thermocouple input interface. The documented communications interface uses Dual RJ-45 Ethernet to IONet. The hardware uses a I/O pack mounted on terminal board form factor. The system architecture should be matched to the documented configuration, including Simplex or TMR per terminal board and pack count. It should be matched with compatible hardware such as STTC/TBTC terminal boards 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.
