Dry contact relayA wireless relay with a voltage-free dry contact that turns appliances and devices on and off, powered by a 7-24 V DC source. Can imitate a button or a switch. Maximum performance: Works up to 1,000 meters from Ajax Hub in open space or across several floors of a business center.Allows for remotely switching connected devices on and off through the app or a browser. Has a pulse equipment control function. Protection from intruders and failure: Protected from power surges and overheating. Response from the relay can be checked every 12-300 seconds. Effortless operation: Uses a remote antenna for better reception. Operating voltage range: 7-24V. Remembers settings after power failure. Simple professional-level installation: Installed inside the connection boxes, electric service panels, or the housings of electric switchboards.
