Relay Pin Terminals

Another step for connecting a relay to the PCB covers the pin terminals and configuration of the relay. The standardized approach shown in the table identifies the terminals of electromagnetic relays.

Terminal	Terminal Description
_COIL	One end of the coil – voltage connects to the terminal to supply power to the coil
COIL	One end of the coil – voltage connects to the terminal to supply power to the coil
COM	This is the output terminal of the relay where one end of the load circuit is connected. This terminal is internally connected with either of the other two terminals depending on the state of the relay.
NO – Normally Open	Connects to device that the relay will power when the coil receives sufficient voltage to energize.  Device remains off when the relay has no power and switches on when the relay receives power.
NC – Normally Closed	Terminal connects to device to power when relay receives no power. Device remains on when the relay has no power and switches off when the relay receives power.
