FIELD: electrical engineering. SUBSTANCE: device for remote control over reversible electric motor drive has A. C. electromagnetic starter with two coils, four make and six break contacts, box with limit switches with break contacts, four diodes, two current limiting resistors, polarity discriminator composed of four diodes and capacitor, two wires of blinking light of positive and negative polarity, signalling wire, two control wires, control elements with two make contacts to send commands OPEN and CLOSE, switching over contact to send command stop, position indicator of shutting element composed of two light-emitting diodes. One leads of contacts are tied up together and are linked to phase wire of power supply source. Diode of forward direction are placed in series between common points of contacts. Device prevents mutual influence of control and signalling circuits. Device makes it possible to connected in parallel any number of position indicators and controlelements. EFFECT: expanded operational capabilities of device. 1 dwg
