2 Pole Relay Wiring Diagram
2 pole relay wiring diagram wiring diagram is a simplified adequate pictorial representation of an electrical circuit.
2 pole relay wiring diagram. Inorder to explain the working of a change over relay i have compared it to a spdt relay. A relay mechanism basically consists of a coil and a spring loaded contact which is free to move across a pivoted axis. Injunction of 2 wires is generally indicated by black dot to the junction of 2 lines.
A spdt relay configuration switches one common pole to two other poles flipping between them. Dpdt relay wiring diagram this is the diagram below to learn all the pin terminals of a double pole double throw dpdt relay. Place the relay s rated coil voltage on these terminals.
A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. In other words it s like two simple switches controlled by a single actuator. Overload relays ac motors dc motors wiring capacitors resistors semiconductors table 1 standard elementary diagram symbols cont d.
The central pole is hinged or pivoted in such a way that when the relay coil is powered with voltage the central pole joins with one of the side terminals of the device called the n o contact normally closed. The square relay pinout shows how the relay socket is configured for wiring.

A wiring diagram is a simplified traditional photographic depiction of an electrical circuit. It has 2 terminals and 4 connectors and you can look at the dpdt relay as the equivalent of 2 single pole double throw spdt relays. Double pole single throw dpdt.
Consider a spdt relay with a common pole c and let the other two poles be a and b respectively. Change motor direction with dpdt relay as you can see in the schematic the 12v battery or use other voltages is connected with the plus at terminal t1 and minus at terminal t2.
