Normally Open Relay 12v

In other words when voltage is applied to the relay contactor terminals this contact closes.

Normally open relay 12v. If connected to nc the load remains connected before trigger. The iso mini relay we have looked at above has 4 pins or terminals on the body and is referred to as a make break relay because there is one high current circuit and a contact that is either open or closed depending upon whether the relay is at rest or energised. Used to trigger on off the relay normally one end is connected to 12v and the other end to ground. Relays with 5 contacts are called changeover relays and are capable of switching between two separate output circuits a normally open circuit and a normally closed circuit.

If the contact is broken with the relay at rest then the relay is referred to as normally open no and if. Normally open no contacts allow current when the relay or contactor is energized.

Similar to a single pole single throw on on switch these relays can change over from one circuit to another and can be used to either turn a circuit on or turn a.

In this episode we will see construction and working of relays and the different types of relays such as normally open and normally closed. Normally close nc the other end of the load is either connected to no or nc.
