FUNCTIONAL DESCRIPTION:

IS200TBTCS1B is a Thermocouple Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. Thermocouple inputs of the 24-type E, J, K, S, or T are supported by the Thermocouple Input (TBTC) terminal board. Only when combined with PTCCH2 in Mark VIe does it accept extra inputs from B, N, and R types of thermocouples? Two barrier-type blocks on the terminal board are connected to these inputs through wiring. Using connectors of the DC variety, TBTC interfaces with the I/O processor. The TBTC is available in the following two varieties:

• TBTCH1C for simplex applications has two DC-type connectors.
• TBTCH1B for TMR applications has six DC-type connectors.

MARK VI SYSTEMS:

TBTC collaborates with the VTCC processor and supports simplex and TMR applications in the Mark VI system. Two cables link one TBTCH1C to the VTCC. TBTCH1B is connected to three VTCC boards in TMR systems using six connections.

INSTALLATION:

The two I/O terminal blocks should receive the thermocouple wires directly. Two screws are used to secure these detachable blocks to the terminal board where they are placed. Each block has 24 terminals that can accommodate wires up to #12 AWG. Each terminal block has a shield terminal strip that is connected to the chassis ground. In Mark VI systems, cable the TBTC J-type connectors to the I/O processors in the VME rack.

OPERATION:

There are two grounding options for the 24 thermocouple inputs. The distance they can be from the turbine control panel is up to 300 m (984 ft), and the maximum two-way cable resistance is 450. As seen in the following graphic, TBTC includes two CJ reference devices and high-frequency noise reduction. For each type of thermocouple, the analog-to-digital conversion and linearization are carried out by the I/O processor. One VTCC is utilized in Mark VI simplex systems that use TBTCH1C. Two PTCC packs plug into TBTC in Mark VIe simplex systems to obtain 24 thermocouple inputs.
