How to Connect an NTC Temperature Sensor to a Smart Relay PLC

I demonstrate how to select, program and add calibration for an NTC temperature sensor connected to a Zelio Smart Relay (mini PLC). The smart relay operates at 24VDC. The NTC connects to an analog input and is configured in a pre-defined function block. I set up a display to show the measured value and show how to calibrate the sensors. system is demonstrated on our SRT100 DAI+ Smart Relay / PLC Trainer, used in Schools and Colleges.
