Ajax Relay – Wireless Low-current Dry Contact Relay


Done On Order – Lead Time 1 – 2 Weeks
A low-current relay to control appliances remotely.


The Ajax Relay fits easily into a junction box, an electrical panel, or a switching unit body. And the flexible external antenna provides stable connectivity. 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.

Connecting Ajax Relay to the hub takes less than a minute — it’s enough to scan a QR code with the Ajax app.
