Relay circuit diagram - 31 100 nike 8 a circuit diagram electrical diagram elementary diagram electronic schematic is a graphical representation of an electrical circuit a pictorial circuit diagram uses simple images of ponents while a schematic diagram shows the ponents and interconnections of the circuit using standardized symbolic representations relay switch circuit relays are electromechanical devices that use an electromag to operate a pair of movable contacts from an open position to a closed position the 2 coil terminals is where the voltage is placed in order to energize the coil place the relay s rated coil voltage on these terminals the polarity of the voltage does not matter usually a relay is used in a circuit as a mag ic switch to turn on a second circuit a relay is an electromag ic switch which is activated when a small current is passed through its coil relay driver circuit using uln2003 featured.

image in general while designing electronics projects the loads are controlled switched on or off using microcontroller block a solid state relay ssr is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals relay is an electromechanical switch used to control protect operate various circuits or system this article discusses a brief on electromechanical relay relay wiring diagram a relay is typically used to control a ponent that draws high erage the relay allows full power to the ponent without needing a switch that can carry the s
