    SD-2xIn: Digital inputs with Ethernet and WiFi


    SD-2xIn is a device for connecting door or window contacts, PIR motion detectors or smoke or gas detectors with a dry contact output. It allows connecting 2 independent sensors.

    For configuration, SD-2xIn features a built-in web server and WiFi connectivity. The device can be monitored remotely over the Internet using the free SensDesk portal and the SensDeskMobile app.
