8 Pin Relay Circuit Diagram. Adjustable timer circuit diagram with relay output. By looking at the diagram below we can go through the basic concept of a relay and how they operate.
In the above 5 pin relay diagram 1 and 2 pins for coil 3 is the common pin 4 is normally close and 5 is normally open pin. This diagram will show you how simple it is to control motors lights valves other relays and any type load you want. As pin 6 is already low the output at pin 3 becomes high.
This diagram will show you how simple it is to control motors lights valves other relays and any type load you want.
Not that his relay can be 5 volts dcv 12 volts dcv 24 volts dcv etc according to ratting voltage of coil. Below given is relay driver circuit to build your own relay module. The extra components apart from the relay are there since it would not be possible to drive the relay directly from the pins of a microcontroller. The pin configuration is shown in the figures.
