Simple Relay Schematic Diagram. Let s say were using household voltage in this circuit which is 110 120 vac. In this example we are simply turning on a light.
In a ladder diagram the two poles of the power source are drawn as vertical rails of a ladder with horizontal rungs showing the switch contacts relay contacts relay coils and final control. Now we present here the same circuit but we make different components selection for better stability the schematic diagram of the circuit is shown in the figure 2. At the initial condition when switch is open no current flow through coil hence common port of relay is connected to no normally open pin so the.
An on off switch is added for the switching purpose of the relay.
Here is one example using 12v relay 220ω and 2200uf capacitor for building 12v flasher circuit. In the above circuit 5v relay is powered by a 9v battery. Relay logic circuits schematic symbols. Assortment of 12 volt relay wiring diagram.
