Manufacturer overview
Dry contact relay to control 12-24 V⎓ power supply remotely
The impulse for smart security. Set the automatic water shut off in case the washing machine breaks or a pipe bursts. Control the water supply at the facility remotely or set up a schedule.
Flexibility at the core. Settings versatility and low power consumption make Relay a universal tool for equipment control. Dry contact is not galvanically connected to the device power supply so that it can be used both in low-voltage and household networks. There are bistable and pulse modes. The relay can be easily connected to a power supply unit paired with a backup battery.
Unique wireless technology. Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.
Smart security for home and business. Use automation scenarios so your security system not only reports threats but also actively counters them.
No extra effort. Connecting Relay to the hub takes less than a minute — it's enough to scan a QR code with the Ajax app. The miniature device (39×33×18 mm) fits easily into a junction box, an electrical panel, or a switching unit body with DIN Holder. And the flexible external antenna provides stable connectivity.
Ajax product categories. In an Ajax system, you can combine devices of all product categories: Intrusion protection, Video surveillance, Fire and life safety, or Comfort and automation. Create the system to suit your needs and manage it in a single interface.
