Which contact arrangement is typical of an industrial control relay? A relay can also be considered as an electrical amplifier for discrete signals. In other words, the device provides the supply voltage AND the input terminals.. you just put the two together to make the circuit. Limit switches. The difference between relays and time delay relays is when the output contacts open & close: on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, the contacts can open or close before or after some time delay. ; . In this condition, the relay is on when the control voltage exceeds the operating voltage. An example of to relay is to get a message to someone. relays, the potential difference between the flavoenzymes FAD/FADH2 centers and those of the bound relays, and the period to 10% loss in substrate-dependent current at a You don't have to worry about PNP or NPN either.. the contacts don't care!
