The analog switching Carlo Gavazzi RM1E solid state relay works in accordance with the phase angle control principle, in which the output switching point in the AC sine wave depends on the control current.
With the Carlo Gavazzi RM1E solid state relay, 4mA corresponds to no switching and 20mA corresponds to full sine wave (near linear power response). The Carlo Gavazzi RM1E solid state relay switches off every time the output current crosses zero and switches ON in accordance with the applied control current.
