Ajax - Wireless low-tension dry contact relay (Ajax Relay)

Relay is a wireless, low-voltage relay featuring potential-free (dry) contacts. Use Relay to remotely switch on/off appliances powered by a 7–24 V DC source. Relay can operate both in pulse and bistable mode. The device communicates with a hub via Jeweller radio protocol. In the line of sight, the communication distance is up to 1,000 m.

The Relay contacts are not galvanically connected to the device itself, so they can be connected to the input control circuits of various equipment to imitate a button, toggle switch, etc.

Use scenarios to program actions of automation devices (Relay, WallSwitch or Socket) in response to an alarm, Button press or schedule. A scenario can be created remotely in the Ajax app.

Principle of operation

The device controls electric power supply by means of relay, which closes and opens the dry contact.

Features

Operates from 7 - 24 V DC voltage sources. The dry contact is not galvanically connected to the device itself.

Installation and set up

The device is installed in junction boxes, distribution boards, and enclosures of switching units.

Safe home and office automation

Boost the potential of your security system with scenarios to actively resist the threats it detects and automate your routines. Set up a Night mode activation on schedule; turn off all the office lights automatically by arming the system; program the outdoor lights to spotlight trespassers when they trigger an outdoor motion detector; or install a sustainable anti-flood system. The system continues to execute scenarios even if the connection with Ajax Cloud is lost.
