AJAX-AD-WS-B

Features:

Safeguard in the power grid
The device connects directly to the 110 V~/230 V~ source and closes/opens the circuit on command. The relay can handle loads of up to 3 kW, which is enough to connect a very power-hungry device. Thanks to WallSwitch, this feature of the device may become known - it displays power consumption in the Ajax app.

• Protects devices against overcurrent and voltage surges
• Operates in bistable or pulse modes
• Allows controlling electricity consumption

No extra effort
Connecting WallSwitch to the hub takes less than a minute - it's enough to scan a QR code with the Ajax app. The miniature relay (39x33x18 mm) is easy to place in a recessed wall plate, the body of an electrical appliance, or an electrical panel with DIN Holder. A flexible external antenna ensures stable communication.

DIN Holder
Bracket to fix Relay or WallSwitch on DIN rail

Always in touch
We developed the Jeweller radio protocol to ensure uninterrupted interaction of all security system devices. The radio protocol uses frames to synchronize device communication, authentication to prevent forgery, and encryption to protect against hacking.

• Two-way communication at a distance of 1000 meters
• 5 radio signal range extenders in the system
• Command delivery in0.15 s
• Adjustable ping from12 s

Smart security for home and business
Use automation scenarios, so your security system not only reports threats but also actively counters them.

• Flood-prevention system
• Site lighting by alarm
• Power shutdown in case of fire
• Presence simulation
• Heating on schedule
• Water
• LeaksProtect
• WallSwitch
• Electrovalve

Relay
Dry contact relay to control 12-24 Vdc power supply remotely
