Low-current relay to control appliances remotely
The impulse for smart security
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.
Pulse 0.5–255 seconds
Power supply 7–24 V DC
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. And the flexible external antenna provides stable connectivity.
