GE IS200TBTCH1C IS200TBTCH1CBB Thermocouple Terminal

The GE IS200TBTCH1C IS200TBTCH1CBB Thermocouple Terminal Board connects thermocouple sensors to the temperature input system. You will find this board essential for accurate temperature measurement in harsh environments. Its built-in isothermal reference block eliminates external cold-junction compensation needs.

Dimensions, Weight, and Mechanical Layout

This thermocouple terminal board measures 20.2 cm in length and 15.0 cm in width. Its height reaches 3.6 cm including all terminal blocks. The total weight stands at 0.51 kilograms for DIN-rail mounting. A fiberglass-reinforced PCB provides excellent thermal stability across the operating range.

Input Interfaces and Component Count

The GE IS200TBTCH1C IS200TBTCH1CBB Thermocouple Terminal Board offers sixteen independent thermocouple input channels. Each channel accepts type J, K, T, E, R, or S thermocouple connections. You also receive an integrated isothermal reference block with precision thermistor. In total, this board contains 142 individual electronic components. These include 16 terminal blocks, 1 reference block assembly, and 96 signal conditioning resistors.

Isothermal Reference and Filtering Features

A solid copper isothermal block maintains all terminal junctions at identical temperatures. The board includes a precision thermistor that measures the block temperature accurately. Each signal path features a passive low-pass filter for noise rejection. Consequently, the board achieves ±0.25°C reference accuracy across the full temperature range.

Environmental Limits and Wiring Specifications

Therefore, the operating temperature ranges from -40°C to +75°C. Storage temperatures extend from -55°C to +85°C without degradation. Each screw terminal accepts 16 to 26 AWG thermocouple extension wire. Maximum terminal torque rating reaches 0.45 Nm for reliable connections.

Connectors, Cabling, and Additional Features

Two 40-pin ribbon cable headers connect to the thermocouple input board. A single shield terminal bar provides earth grounding for cable shields. For similar static trip system temperature termination, see the RMS-TSG-TZ-C model from the same manufacturer. However, this thermocouple terminal board specializes in isothermal reference termination exclusively. Mean time between failures (MTBF) exceeds 260,000 hours due to passive design.
