GE IS200STTCH2A Thermocouple Terminal Board

Product Description: The IS200STTCH2A is a simplex thermocouple terminal board for GE Speedtronic Mark VI / Mark VIe and EX2100 excitation control systems. It serves as the field wiring termination interface for thermocouple temperature sensors, providing cold junction compensation, signal filtering and isolation before sending temperature signals to the main I/O module. It accepts thermocouple inputs and can also be configured for 24V dry contact signals, collecting turbine casing, bearing and exhaust temperature data for monitoring and protection interlocks.

Features:

• Designed for GE Mark VI, Mark VIe and EX2100 turbine control platform
• 24-channel thermocouple input termination with cold junction compensation
• Built-in EMC filtering and surge suppression for noisy power plant cabinet environments
• DIN rail mounting with 48-position screw terminal block for easy field wiring
• Simplex non-redundant temperature interface board
• Compatible with common thermocouple types used on gas and steam turbines
• Standard IS200 series terminal board form factor matching Mark VI rack layout

Applications:

• Gas turbine and steam turbine temperature monitoring cabinet
• EX2100 generator excitation system temperature signal collection
• Thermal power plant turbine protection and temperature alarm interlock
• Oil & gas compressor turbine control system spare replacement
• Legacy Mark VI system retrofit and maintenance projects

FAQ:

Q: What does STTC stand for in IS200STTCH2A?
A: STTC = Simplex Thermocouple Terminal Card, simplex non-redundant thermocouple terminal board.

Q: Can it work on Mark VIeS system?
A: It is mainly for Mark VI / Mark VIe; confirm firmware and backplane version before installation.
