The analog switching relay works in accordance with the phase angle control principle, i.e., the output switching point in the AC sine wave depends on the control input which can be either 4-20mA. 4mA correspond to zero output power whilst 20mA correspond to full output power ( near linear power response ). The relay switches off every time the output current crosses zero, and switches ON in accordance with the applied control input.
