Abstract

The control circuit is connected to an electronic switch, connected to a load circuit (Ph,Mp). The control circuit has voltage supply (A1,A2,D1-D4,C) which is galvanically separated from the load current circuit. The control circuit consists of a series link of a pushbutton (Ta) connected in parallel to a variable resistor (R1), a current relay (Re) with a working contact in the load circuit, and an evaluator with a thyristor (Th). A series-connection of a resistor (R2) and a LED of an optocoupler (Ok) is connected between the thyristor anode and cathode such that the current flow in the forward direction of the LED is in the direction of the tyristor cathode. One or more diodes (D5,D6) are connected in series with the same directional sense between the thyristor anode and the gate so that the diode anode is connected at the anode of the thyristor, and the cathode of the diode(s) to thyristor the gate. The collector of the output transistor of the optocoupler is connected with the control input of the electronic switch. ADVANTAGE - Simple, single control line facility for loading switching, and its power control.
