Product information

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.

Pulse 1–255 seconds
Power supply 7–24 V⎓
Dry contact

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.

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 up to 1000 meters
5 radio signal range extenders in the system
Command delivery in 0.15 s
Adjustable ping from 12 s
