4. Functionality
The Axiom AX750T functions as an intermediary interface between field devices and electronic control or measurement systems. It simplifies wiring by providing screw terminals for field connections and a flat cable connector for system-side interfacing.
Working Principle:
- Field signals (analog, digital, or thermocouple) are wired to the screw terminals.
- Each terminal corresponds to a pin on the 50-pin flat cable connector, ensuring one-to-one signal mapping.
- The integrated cold junction compensation circuit stabilizes thermocouple reference points, allowing accurate temperature measurement when connected to compatible DAQ or control modules.
- The flat cable transmits signals to the host system, such as a PLC, data acquisition board, or signal conditioning module.
Use Cases and Applications:
- Industrial automation and process control systems
