RM1E48AA50 Semiconductor relay RM, proportional, 1 pin, 50 A, 200 - 550 V A

The analogue switch operates according to the principle of phase-angle control, i.e. the switching point on the half-sine wave in the load circuit depends on the control current. At 4 mA/0 V, the load circuit does not switch. 20 mA/10 V corresponds to a full wave (almost linear power transfer). The relay switches off every time the load current drops to zero. It switches on according to the control current/control voltage.
