Cold Junction Compensation and Channel Signal Accuracy
The 1794-CJC2 provides thermistor-based cold junction compensation for compatible Flex I/O thermocouple input modules. The accessory measures terminal temperature conditions through the terminal base connection, allowing the input module to apply compensation calculations to thermocouple measurements.
The kit supports thermocouple signal processing applications across 1794 FLEX, FLEX EX, and FLEX XT I/O families. Correct installation maintains the reference temperature point required for thermocouple measurement conversion.
The DIN rail mounted terminal base configuration supports integration within Flex I/O modular assemblies while maintaining the physical connection between the compensation sensor and the temperature input channel.
