With the WiDom Relay with Dry Contact you get the possibility to integrate existing electrical installations with an independent power supply, such as solenoid valves (e.g. gas, water and irrigation) or power operated valves, into your existing Z-Wave network.The compact radio module is placed in a wall box right behind the normal switch turns your normal electrical installation into a Z-Wave base Smart Home. The button or switch is no longer directly switches the load but acts as an input for the WiDom insert that is controlling the load. The switch only sends control signal to the insert which controls the load again. Furthermore the connected switch can start different scenes in a Z-Wave gateway. With the LED you get feedback directly if the electrical connections are correct. Thus the installation is much more easy. Furthermore the WiDom Relay with Dry Contact acts as a repeater and increases the reliability of your Z-Wave network. Equipped with contact protection technology (zero crossing) ensures a longer product life by reducing the electrical stress.Features:Flush-mounted module with dry contact outputIntegrates electrical installations with an own power supply (like valves) into your Z-Wave networkWorks with every type of external switchScene activation and timer function for switching ON/OFF the loadContact protection technology (zero crossing)Power supply: 230V, 50/60HzMaximum load: 13A (resistive)Wireless technologie: Z-Wave PlusDimensions: 37x37x17mm
