Relay Installation Diagram Sense Circuit
Relays are switches that gaping and close circuits electromechanically or electronically. Relays control 1 circuit by opening and windup contacts in another circle. As relay diagrams show, when a relay contact is unremarkably open (NO), there is an unrestricted contact when the relay is not energized. When a electrical relay contact is Normally Closed (NC), at that place is a winking meet when the relay is not energized. In either case, applying electrical current to the contacts will change their state. Relay race are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices omit for small motors and Solenoids that force low amps. Nevertheless, relays can "see to it" larger voltages and amperes away having an ...
