Contactor Relay Circuit Diagram. Select libraries from electrical engineering section. Similarly circuit breakers are called q because iec 60750 says so.
A wiring diagram is a streamlined conventional photographic representation of an electric circuit. This figure shows a basic relay logic circuit. The diagram above is the 5 pin relay wiring diagram.
The figure consists of two circuit diagrams such as relay internal circuit and the external control circuit.
As relay diagrams show when a relay contact is normally open no there is an open contact when the relay is not energized. This diagram will show you how simple it is to control motors lights valves other relays and any type load you want. The diode prevents relay from arcing by giving a return path for the energy stored in the magnetic field of coil extending the life of relay. Some contactors provide an auxiliary output contact as a signal to the isolated part of the circuit that the contactor has been energized.
