Ajax Wireless Relay Switch

Description

Compact and wireless relay module that allows you to remotely control electrical devices via your Ajax hub and the Ajax app. It is used to control low-voltage equipment (e.g. electric locks, valves, pumps, lighting or other auxiliary systems) by closing or opening a dry contact (NC/NO). The relay has adjustable modes (bistable or pulse mode) and can be triggered manually from the app, automatically via scenarios (such as in case of alarm, disarm or time schedule) and is suitable for mounting in a junction box, electrical panel or appliance box.
