How do you wire up a relay?
A relay is an electrically operated switch. It consists of a coil of wire wrapped around an iron core, which creates a magnetic field when current is passed through it. This magnetic field can then be used to operate a switch, which in turn can control a circuit.
What is 87 and 87a on a relay?
87 and 87a are the two contacts on a relay that are responsible for turning the relay on or off. When current flows through the 87 contact, it turns the relay on, and when current flows through the 87a contact, it turns the relay off.
What is L1 and L2 in a relay?
L1 and L2 refer to the two legs of the relay. L1 is the "control" leg, which is used to turn the relay on and off. L2 is the "load" leg, which is used to power the load that the relay is controlling.
What are the 5 pins on a relay?
The 5 pins on a relay are the control, ground, power, normally open, and normally closed. The control pin is used to turn the relay on or off. The ground pin is used to connect the relay to the ground. The power pin is used to supply power to the relay. The normally open pin is used to connect the relay to the load when the relay is turned on.
What is 85 and 86 on a relay?
85 and 86 on a relay are the two poles that complete the circuit. The circuit is broken when the relay is open, and closed when the relay is closed.
