Relay


Dry contact relay to control 12-24 V⎓ power supply remotely
Pulse 1–255 seconds
Power supply 7–24 V⎓
Dry contact

Flexibility is fundamental

With its low power consumption, Relay is a versatile instrument for equipment control. Its’ dry contact can be utilised in both low-voltage and domestic networks because it is not galvanically coupled to the device power supply. There are pulse and bistable modes. The relay is simple to link to a power supply unit and a backup battery.

Never miss a beat

The Jeweller radio protocol was created by Ajax to guarantee the continuous operation of all security system components. The radio protocol uses frames to synchronise device communication, authentication to prevent spoofing, and encryption to prevent hacking.

Intelligent home and business security

Utilize automation scenes to enable your security system to actively defend against threats in addition to reporting them.

Installation with no added effort

Scanning a QR code with the Ajax app is all it takes to connect Relay to the hub in under a minute. This tiny device (39x33x18 mm) makes it simple to insert into a junction box, electrical panel, or switching unit body. Additionally, the adaptable external antenna offers dependable connectivity.
