AJAX - Wireless dry contact relay

Radio channel controller for remote control of low current equipment. It is used to activate electric locks, gates and swing gates, rolling shutters and blinds, and to restart modems and routers.

• Authentication to prevent forgery

• Jamming detection and communication channels encryption

• Protected from power surges and overheating

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.
