Description
The IS200STTCH2A is a dedicated thermocouple input module for General Electric (GE) Mark VI series control systems and is part of the temperature signal acquisition units in the I/O package series. This module is specifically designed for industrial gas turbines, steam turbines, and generator sets. It converts temperature signals (such as Type J, Type K, and Type T) collected from field thermocouple sensors into digital signals for use by the control system in monitoring, protection, and closed-loop control.
The module features a Eurocard form factor and supports VME bus backplane communication. The front panel is equipped with two DB37 high-density D-sub connectors, allowing connection of up to 16 independent thermocouple channels (some configurations include an 8-channel terminal block with dedicated cold-junction compensation terminals, depending on the specific terminal block model selected). It also incorporates a high-precision cold-junction compensation (CJC) circuit to ensure measurement accuracy across the full range.
Installation Steps
- Check the chassis slots: Verify that the target slot is a VME bus slot (not a P0 power slot), and ensure there is at least a 10 mm cooling gap between adjacent slots.
- Insert the module: Align the module's top and bottom rails with the rack slots, then push it in evenly until the backplane connector is fully engaged. After hearing a "click," tighten the top and bottom mounting screws (torque: 0.5-0.6 N*m).
- Install the terminal block: Secure the IS200TBTCH2A terminal block inside the cabinet using a DIN rail or mounting plate, ensuring it is no further from the module body than the cable's length allows.
- Connect the cable: Use a pre-terminated shielded cable to connect the DB37 connector on the module's front panel to the corresponding connector on the terminal block, then tighten the locking screws (pay attention to the direction to prevent misalignment).
- Connect the thermocouple: Connect the field thermocouple compensation leads to the corresponding "+" and "−" terminals on the terminal block according to their polarity, and ground the shield at one end on the terminal block side.
Case Studies
At a petrochemical company's on-site power plant, the steam turbine bearing shell temperature is monitored using a single-module, single-channel data acquisition system. Two IS200STTCH2A modules are configured with DMR redundancy, with each module independently acquiring data from two PT100 thermistors on the same bearing.
This not only prevents temperature signal loss and subsequent emergency tripping caused by module failures; but also enables redundant temperature signal acquisition. In the event of a failure in either module, the system automatically switches to data from the backup module, ensuring that the unit operates without any unplanned downtime throughout the year.

FAQ
What are the main differences between the IS200STTCH2A and the IS200STTCH1A?
The main differences include: (1) The number of channels on the STTCH2A has been upgraded from 8 to 16; (2) Support for Type N and Type B thermocouples has been added; (3) CJC accuracy has been improved from ±1°C to ±0.5°C; (4) It is compatible with the higher-speed UDB communication protocol, increasing the data refresh rate to 100 ms (previously 200 ms).
Is it necessary to power down the system when replacing a module?
In a DMR/TMR redundant configuration, hot-swapping is supported without the need to power down the system. However, in a single-module configuration, the system must be shut down before replacement; otherwise, the signal from that measurement point will be lost, which may trigger a protection action.
What is the warranty period for this module?
Typically, the warranty period for original products is 12 months.
