Introduction
Applicable for appliances: VT825 & VT825DC with VT18 / extension module, VT900, VT960 VT825i, VT825ii, VT855i, VT855ii, VT960i, VT960ii.,
These systems have the possibility to can connect up to x2 loads managed by built-in relays. Built-in relays have independent separate entrances and exits. The appliances use latching relays, when the power on the appliance switches on/off, relays remain in the command position!
Purpose
Relays are needed for control of AC/DC mains: e.g. lamps, fans, or other devices.
| Warning |
|---|
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.
...
NC (Normally Closed): A normally closed configuration is used when you want to turn off the relay by default. In this configuration, the relay is always closed and remains closed until you send a signal from the Vutlan monitoring system to the relay module to open the circuit.
NO (Normally Open): A normally open configuration works the other way in which the relay is always open until you send a signal from the Vutlan monitoring system to the relay module to close the circuit.
