ADI's DEMO-AD7124-DZ printed circuit board has additional features for easy system evaluation. RTD, thermocouple or pressure sensor can be connected through the eight-pin connector J5. The device has test points for HART RTS and CD. The four-pin connector enables code to be downloaded to the microcontroller.
The CN-0382 design support package also includes all-field instrumentation C code examples for three- and four-wire Pt100 and Pt1000 RTDs, thermocouples, and voltage / current excited pressure sensors. This allows a complete evaluation and verification of all hardware modules and functions of the circuit, and a limited verification of HART interface functions.
