Basic Relay Operation for RF controller

Postby admin » Fri Jun 12, 2009 2:54 pm

A relay is just like a 'switch' but with power control the On and Off function. There is no voltage or current coming out from the relay contacts unless you inject power sources. Rememter, it is a SWITCH!

NO = Normally Opened
NC = Normally Closed

NO become Closed once the relay's coil energized.
