Relay jxj abbreviation

Relay, also known as relay, is an electronic control device. It has a control system (also called input loop) and a controlled system (also called output loop), which is usually used in automatic control circuits. It is actually an "automatic switch" that controls a large current with a small current. Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. The relay coil is represented by a long square symbol in the circuit. If the relay has two coils, draw two parallel long boxes. At the same time, the literal symbol "J" of the relay is marked in or beside the long box. There are two representations of relay contacts: one is directly drawn on one side of a long box, which is more intuitive.
