Hvac blower time delay relay icm 102 90 340 dpdt relay duration. 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. Dpdt relay wiring diagram this is the diagram below to learn all the pin terminals of a double pole double throw dpdt relay. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.
Wire a dpdt rocker switch for reversing polarity. The 2 coil terminals is where the voltage is placed in order to energize the coil. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. When you need to control a dc motor such as a dc linear actuator you usually need to be able to swap the polarity on the wires going to the motor. When the relay receives 12 volts of power the relay snaps from the nc position to the no position. 6 pin dpdt switch wiring diagram dpdt relay wiring diagram fresh dpdt switch wiring diagram guitar save dpdt switch wiring diagram.

The red led and the dc fan now shut off and the green led and the dc motor now turn on and operate. Spdt relay dpdt relay by circuit diagram relay is a electro mechanical switch used to control high power application through low power signal electronic circuits for an example a simple timer circuit working under 5v dc bias can not control high voltage light bulb by introducing relay component we can easily control light bulb. Place the relays rated coil voltage on these terminals.
