Functional Description

• The IS200TBTCH1B serves Mark VI and Mark VIe turbine control systems.
• It natively accepts 24 type E, J, K, S, or T thermocouple inputs.
• It supports additional B, N, and R types only with PTCCH2 in Mark VIe systems.
• Thermocouple inputs connect to two barrier-type terminal blocks.
• The board communicates with the I/O processor through DC-type connectors.
• TBTCH1C suits simplex applications and uses two DC-type connectors.
• TBTCH1B suits TMR applications and uses six DC-type connectors.
• In Mark VI systems, TBTC works with the VTCC processor.
• A single TBTCH1C connects to one VTCC using two cables.
• A TBTCH1B connects to three VTCC boards using six cables.
• Mark VI systems handle 24 inputs, while Mark VIe systems handle 12 inputs.

Installation Guide

• Connect thermocouple wires directly to the two I/O terminal blocks.
• These removable blocks mount on the terminal board and secure with two screws.
• Each block contains 24 terminals that accept up to #12 AWG wires.
• A shield terminal strip connects to chassis ground on the left side of each block.
• For Mark VI systems, cable the TBTC J-type connectors to I/O processors in the VME rack.
• Keep thermocouple inputs within 300 meters of the turbine control panel.
• Maintain two-way cable resistance below 450 Ω for reliable operation.

Operation Notes

• The 24 thermocouple inputs can be grounded or ungrounded.
• The board provides high-frequency noise suppression for stable readings.
• Two cold junction reference devices support accurate temperature measurement.
• The I/O processor manages analog-to-digital conversion and linearization.
• Mark VI simplex systems use TBTCH1C with one VTCC processor.
• Mark VIe simplex systems use two PTCC packs plugged into the TBTC.
• TMR systems use TBTCH1B, where thermocouple signals fan out to three J-connectors.
• The TBTC board supports all thermocouple spans documented for its I/O processor.
