The new Web-IO 4.0 Digital, 1x230V In, 1xRelay Out monitors and switches mains voltages up to 230V over TCP/IP Ethernet. In the simplest case the Web-IO can be operated directly from the browser or conveniently using an app.

Thanks to MQTT and REST support IoT and Industry 4.0 applications become child’s play. Like all Web-IOs, the new model 57732 also supports proven industry protocols such as OPC and Modbus/TCP. Sending of e-mail messages, e.g. when there is a power failure, is just one of many possible applications.

If you would like to find out what else the Web-IO 4.0 can do, simply order a sample for testing with no obligation.
