GE IS200TBTCH1CBB Thermocouple Input Terminal Board
Product Details:
The GE IS200TBTCH1CBB is a Thermocouple Input Terminal Board in the Mark VI Series, integral to GE’s Distributed Turbine Control Systems.It accepts 24 thermocouple inputs via two barrier-type terminal blocks, supporting both grounded and ungrounded thermocouples up to 300 meters from the control panel.
Communication with I/O processors uses DC-type connectors, with configurations for simplex (TBTCH1C, 2 DC connectors) or TMR (TBTCH1B, 6 DC connectors) setups. Equipped with high-frequency noise suppression and two cold junction reference devices, it ensures signal integrity. Analog-to-digital conversion and linearization occur in the I/O processor, with PTCC I/O packs handling processing in Mark VIe systems.
Features:
24 Input Channels: Supports 24 thermocouple inputs (E, J, K, S, T) with a -8.0 mV to +45.0 mV range, suitable for diverse temperature measurements.
Dual Configurations: Compatible with simplex or TMR systems, with TMR distributing signals to three processors for redundancy.
Noise & Signal Protection: Integrates high-frequency noise suppression and cold junction references (-30°C to 65°C) to maintain accuracy; shield terminal strips reduce electrical interference.
Flexible Installation: Terminal blocks accept up to #12 AWG wires, with J-type connectors for I/O pack integration, scalable for redundancy needs.
Fault Tolerance: Cold junction faults trigger backups, ensuring reliability in critical industrial environments.
