Relays are needed for control of AC/DC mains: e.g. lamps, fans, or other devices.

The maximum possible output current of the relay is 10A. The maximum voltage for DC current is 9-30V. |
Function
A relay is an electromagnetic switch operated by a relatively small current that can control a much larger current.
...
NO (Normally Open): A normally open configuration works the other way in which the relay is always open until you send a signal from Vutlan monitoring system to the relay module to close the circuit.
