The GE IC695ACC600 is an RX3i Cold Junction Compensation (CJC) Kit. It is an accessory specifically for use with certain analog input modules in the GE PACSystems RX3i platform.
Key Features
- Purpose: This kit is used to provide accurate cold junction compensation for thermocouple temperature measurements. Cold junction compensation is essential for thermocouples to correct for the temperature at the point where the thermocouple wires connect to the measurement device (the “cold junction”). Without it, temperature readings would be inaccurate.
- Components: The kit typically includes:
- One or more CJC terminal blocks (e.g., IC695TBC001).
- Mounting hardware and labels.
- Compatibility: The IC695ACC600 is designed to work with specific RX3i analog input modules that support thermocouples but do not have built-in CJC. An example of a compatible module is the IC695ALG600 Universal Analog Input Module.
- Functionality: By installing this kit, you provide a stable, temperature-compensated connection point for the thermocouples, ensuring the readings sent to the PLC are accurate across the entire temperature range of the application. The CJC sensor within the terminal block measures the ambient temperature, and the module’s firmware uses this value to correct the thermocouple’s millivolt reading.
Applications
The IC695ACC600 is used in industrial automation and process control applications where precise temperature measurement with thermocouples is critical. It is a necessary component for:
- Power Generation: Monitoring turbine and generator temperatures.
- Process Control: Regulating temperatures in chemical reactors, ovens, and furnaces.
- Any industrial application using thermocouples with a compatible RX3i module.
