The GE IS200TBTCH1C IS200TBTCH1CBB terminates thermocouple signals for temperature monitoring. This board connects various thermocouple types to the main control system. It fits directly into GE Mark VIe and EX2100 applications. You will use this unit for accurate exhaust and bearing temperature measurement.
Technical Specifications Overview
This thermocouple terminal board features 16 isolated input channels for temperature sensors. Each channel accepts J, K, T, or E type thermocouple inputs. The GE IS200TBTCH1C IS200TBTCH1CBB includes a built-in cold junction compensation circuit. A dedicated precision amplifier conditions each millivolt signal before transmission. Consequently, you achieve accurate temperature readings without external signal conditioning.

Internal Components and Energy Storage
The GE IS200TBTCH1C IS200TBTCH1CBB contains one main PCBA with 162 discrete components. Key parts include 16 instrumentation amplifiers and two cold junction sensors. The board also holds four electrolytic capacitors storing 560 µF of energy. This storage filters noise on the analog supply rails effectively. Moreover, a multiplexer sequentially routes each channel to the output connector. Each input includes a differential low-pass filter for noise rejection.
Physical Interfaces and Connectors
You will find one rear-facing 40-pin connector on this board. This connector links to the Mark VIe analog input board for data transfer. Sixteen front-facing screw terminals accept thermocouple wires directly. A separate 2-pin header provides access to the cold junction temperature reading. Four green LEDs indicate power status and backplane communication. One red LED lights for any internal circuit fault. Six mounting holes secure the GE IS200TBTCH1C IS200TBTCH1CBB firmly to its mounting plate.
Installation and Operational Reliability
Install this thermocouple terminal board away from heat sources and fans. Use extension wire matching the thermocouple type for best accuracy. The board automatically compensates for ambient temperature changes at the terminals. Therefore, you receive correct measurements without manual offset adjustments. This unit supports continuous temperature monitoring in gas and steam turbines.
