GE IS200TBTC1CBB Thermocouple Terminal Board

Product Description

GE IS200TBTC1CBB is a TBTC thermocouple terminal board designed for GE Mark VI / Mark VIe Speedtronic turbine control system. It is conformal coated and equipped with 24 thermocouple input channels, supporting E, J, K, S, T thermocouple types. This board acts as the field wiring interface between thermocouple sensors and the matching VTCC / PTCCH2 I/O processor pack, with built-in cold junction compensation for accurate temperature measurement in turbine control cabinets.

Product Functions

• Provide termination for up to 24 thermocouple temperature input signals
• Integrate cold junction compensation circuit to eliminate temperature measurement error
• Signal filtering and surge protection to suppress EMI noise from field cables
• Transmit low-level millivolt thermocouple signals to VTCC or PTCCH2 processor pack
• Support simplex configuration and compatible with TMR triple modular redundant racks
• Monitor surface temperature of turbine casing, exhaust, pipes and hot components

Applications

• Gas turbine and steam turbine casing & exhaust temperature monitoring
• Power plant combined-cycle unit Mark VIe control cabinet spare replacement
• Oil & gas turbomachinery high-temperature point measurement
• Generator and boiler auxiliary thermal condition supervision
• Retrofit and maintenance of legacy Speedtronic turbine control systems
