Proper Way of Wiring 8pin 120ac Volts Coil Relay what is the proper way of wiring a 8pin 120ac volt coil ice cube relay, if somebody can give any tips I will appreciate, I need to control a N/O limit switch to activate a hydraulic motor (chain conveyor)and when the chain conveyor is activated by N/O LS, the 2nd limit in N/C position to stop the signal( I need the N/O Ls when it closes to stay close until 2nd N/C brakes signal and stops the The Basics of Control Relays | EC&M A DC relay showing pole-piece inside of the coil; Also known as ice-cube relays, plug-in relays are inexpensive, widely available, The user may wish to operate controls from 120VAC due to long lengths of field wiring. A plug-in control relay works handily to provide the How To Wire A Relay A relay is switched by electrical power and not a human. This is done by energizing a coil which is internal to the relay and by energizing the coil, the relay changes state just like a wall switch would. Therefore when you energize a relay, you are switching circuits off and on.
