Relay

42,00

Relays allow you to control and automate electric locks, gates, boilers, and other appliances using the Ajax apps. Use scenarios to set up automation workflows on schedule or in response to detector alarms and changes of the system modes.

Pulse 0.5–255 seconds
Power supply 7–24 V DC
Dry contact

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. 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, control opening-closing via the app or using Button, block access to premises by alarm or Night Mode activation and sleep calmly.

Installation and set up

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.
