IS200TBTCH1CBB GE MKVI,THEROCOUPLE TERMINAL BOARD-colletplc

Description:

IS200TBTCH1C is a Thermocouple Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The thermocouple terminal board accommodates up to 24 thermocouple inputs of types E, J, K, S, or T. These inputs are connected to two barrier-type blocks on the terminal board, and communication with the I/O processor is established through DC-type connectors. In the Mark VIe system, the PTCC I/O pack collaborates with the board, supporting simplex, dual, and TMR (Triple Modular Redundant) systems. In simplex configurations, two PTCC packs can be plugged into the TBTCH1C, providing a total of 24 inputs. When using the TBTCH1B, one, two, or three PTCC packs can be connected, supporting a range of system setups, although only 12 inputs are accessible in this configuration.

INSTALLATION:

Mounting Removable Terminal Blocks: The installation process begins by mounting the removable terminal blocks onto the thermocouple terminal board. These blocks serve as the pivotal connection points for the thermocouples within the system. Securing them in place with two screws ensures stability and a dependable connection.

Connecting Thermocouples: Thermocouples, essential temperature sensors, are then wired directly to the terminals on these blocks. Each terminal block comprises 24 terminals capable of accommodating wires up to 12 AWG in size. These terminals provide a secure attachment point for the wires originating from the thermocouples, ensuring a reliable connection.

Shield Terminal Strip for Grounding: Positioned on the left side of each terminal block is a shield terminal strip that connects to the chassis ground. This component assumes a critical role in grounding and shielding the thermocouple wires, mitigating interference, and preserving the accuracy of temperature measurements.

Cabling in Mark VIe Systems: For Mark VIe systems, the connection setup involves I/O packs that plug directly into the J-type connectors on the thermocouple terminal board. The number of cables or I/O packs utilized depends on the desired level of redundancy for the system. Redundancy ensures system reliability by providing backup components, contributing to uninterrupted operations.
