2 Changeover Relay Wiring

In fig 2 different connection and wiring diagrams are shown for a two pole single phase manual changeover switch.

2 changeover relay wiring.

Pin 87 normally open contact. The most common changeover function relays are produced to switch a single feed line usually positive position 30 between two active functions in a circuit the relay is switched manually via a toggle push switch or remotely through the circuit. The upper portion of the changeover switch is directly connected to the main power supply while the lower first and right connections slots are connected to the backup power supply like generator or inverter. 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.

Assortment of 12 volt relay wiring diagram. 12v changeover relay wiring diagram wiring diagram is a simplified customary pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the capacity and signal associates with the devices. Normally open or normally closed. It reveals the components of the circuit as simplified shapes and also the power and signal connections in between the tools.

Pin 86 switch.

The 9 5mm wide terminals tend to be used for higher power applications such as for starter motor solenoid activation and the smaller terminals tend to be used for electronics. There are 2 types of 4 pin relay available. 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. Pin 85 earth.

4 pin relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. A changeover relay differs from a standard relay due to the fact that it is acts as a normally closed relay until the coil windings are energised. Pin 87a normally closed contact. A normally open relay will switch power on for a circuit when the coil is activated.
