AirShield Dual-Channel Relay: switch two groups wirelessly
With this relay module you switch two separate groups of mains voltage from your AirShield system. Think of outdoor lighting and a gate, or two lighting groups that you want to be able to operate separately.
The module (Dahua DHI-ARM7022-W2(868)) has two relay outputs and two switching inputs. Each input controls its own output, so besides the app you can also keep operating it with an existing switch. It fits in a flush-mounting box and can therefore be concealed from view.
Why this relay module
Two separate channels
Two relay outputs that you switch independently of each other: 100-240 VAC and 10 A per channel, up to 16 A combined.
Also with a switch
Two switching inputs, each linked to one output. Your existing wall switch therefore keeps working.
Encrypted connection
Two-way RF in the 868 MHz band with AES128 encryption and frequency hopping.
Concealed mounting
Compact enough for a flush-mount box (47 x 47 x 24 mm), can be mounted with a bracket or in an 86 mm flush-mount box.

No AirShield system yet?
This extension works with the wireless AirShield hub from Dahua. Put your system together with the configurator, or have everything installed by our VEB-approved installers.
Frequently asked questions
Can I switch the two channels separately?
Yes. You switch both outputs independently of each other, in the app or via the associated switching input.
How much may I connect to it?
10 A per channel at 100-240 VAC. The two channels together may be loaded up to 16 A.
Will my wall switch keep working?
Yes. Each switching input controls its own output, so operation with a switch remains possible.
May I connect this myself?
The module operates on mains voltage. Have it connected by a qualified person, or have our installers fit our system.
