FUNCTIONAL DESCRIPTION:
IS200TBTCH1B is a Thermocouple Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Thermocouple Input (TBTC) terminal board accepts 24-type E, J, K, S, or T thermocouple inputs. It accepts additional B, N, and R types of thermocouple inputs only when used with PTCCH2 in Mark VIe. These inputs are wired to two barrier-type blocks on the terminal board. TBTC communicates with the I/O processor through DC-type connectors. Two types of TBTC are available, as follows:
In the Mark VI system, TBTC works with the VTCC processor and supports simplex and TMR applications. One TBTCH1C connects to the VTCC with two cables. In TMR systems, TBTCH1B connects to three VTCC boards with six cables.
INSTALLATION:
Connect the thermocouple wires directly to the two I/O terminal blocks. These removable blocks are mounted on the terminal board and held down with two screws. Each block has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to the chassis ground is located on the left side of each terminal block. In Mark VI systems, cable the TBTC J-type connectors to the I/O processors in the VME rack.
OPERATION:
The 24 thermocouple inputs can be grounded or ungrounded. They can be located up to 300 m (984 ft) from the turbine control panel with a maximum two-way cable resistance of 450 Ω. TBTC features high-frequency noise suppression and two CJ reference devices, The I/O processor performs the analog-to-digital conversion and the linearization for individual thermocouple types. In Mark VI simplex systems using TBTCH1C, one VTCC is used. In Mark VIe simplex systems, two PTCC packs plug into TBTC, obtaining 24 thermocouple inputs. For TMR systems using TBTCH1B, the thermocouple signals fan out to three J- connectors. The Mark VI system accommodates 24 inputs and the Mark VIe system accommodates 12 inputs. The TBTC terminal board supports all thermocouple spans documented for the associated thermocouple I/O processor.

What types of thermocouples are supported by the board?
It is designed to accept inputs from 24 different types of thermocouples, specifically types E, J, K, S, or T, catering to diverse temperature sensing requirements.
How are thermocouple inputs connected to the board?
The thermocouple inputs are wired to two barrier-type blocks on the terminal board. These blocks provide a secure and organized connection point for the thermocouple wires.
How does the TBTC board communicate with the I/O processor?
Communication between the TBTC and the I/O processor is facilitated through DC-type connectors. These connectors ensure efficient data transmission between the thermocouple inputs and the processing unit.
