Hi;
I have installed a temperature and humidity sensor Autonics THD-R-C which gives 4-20mA signal out. The signal is connected with Fatek PLC’s analog input card. This is first time I am working with 4-20mA analog signal rather 0-10V for which I need some guideline to get the signals scaled.
According to manual of sensor, at -19.9C it gives 4mA and at 60C it gives 20mA. In PLC, the coding format is 14bit (0 – 16380). Now how do I scale the values to get exact temperature data in PLC?
