WebbRelay Switch Circuit. Relays are electromechanical devices that use an electromagnet to operate a pair of movable contacts from an open position to a closed position. The advantage of relays is that it takes a relatively small amount of power to operate the relay coil. However a relay switch circuit can be used to control motors, heaters, lamps ... WebbHere, we will emulate the exact same high-pressure alarm circuit using a Siemens S7-1200 PLC instead of a relay coil: Wiring diagram: Ladder Logic Program: Suppose a fluid pressure of 36 PSI is applied to the pressure switch. This is less than the switch’s trip setting of 50 PSI, leaving the switch in its “normal” (closed) state.
