The GE IS200VTCCH1CBB, also cataloged as the VTCC Thermocouple Input Terminal Board, provides direct thermocouple signal interfacing for Mark VI turbine control systems. It supports multiple thermocouple types and transfers conditioned signals into the control rack for processing.
Hardware Specifications
Part Number: IS200VTCCH1CBB
Manufacturer: GE Motors and Industrial Systems
Series: Mark VI
Product Type: Thermocouple Input Terminal Board
Functional Acronym: VTCC
Thermocouples Supported: E, J, K, S, T types
Instruction Manual: GEH-6421
Profinet / EtherNet/IP Deterministic Networks
The IS200VTCCH1CBB integrates with Mark VI backplane communication, maintaining deterministic signal transfer across Profinet and EtherNet/IP networks. This ensures precise synchronization of thermocouple input data with turbine control logic. I/O density scaling is achieved through multiplexed input channels, allowing multiple thermocouple types to be processed without cross-channel interference.
Frequently Asked Questions
Q: Which thermocouple types are supported? A: The board supports E, J, K, S, and T type thermocouples.
Q: What installation rack is required? A: The IS200VTCCH1CBB is installed in the Mark VI turbine control system rack.
