4-20mA Signal Generator (Current Generator)

4-20mA signals are popular and have multiple uses. However testing and generating current signals from microcontrollers/PLC is difficult and requires complex circuits. This module can be used to generate a 4-20mA current signal. It comes with a knob to vary the signal and a display to view the current signal value. Useful for simulating sensor signals, testing 4-20ma circuits, calibrating microcontroller/PLC ADCs, etc.
