Flexible IO access with Web-IOs 57733 and 57738 for automation and IoT applications.

When the need is to control and monitor switching signals over the network, the Web-IO products have long been the best choice. The two latest models are even more flexible when it comes to integrating into the world of automation technology and the IoT – thanks to numerous supported protocols and, depending on the need, usable in- and outputs.

Of special note are all the ways to use both models: in addition to email and MQTT, you can use HTTP(S), REST, OPC UA and DA, Modbus-TCP and FTP and even Socket-API for integrating into traditional automation environments as well as Industry 4.0. With their new, compact housings, both models are ideal for installation in a control cabinet and sub-distribution panel.

The Web-IO 4.0 Digital 4xIn/Out #57733 also provides four IO channels which can be used as inputs or as 24V outputs. If you need potential-free contacts, the Web-IO 4.0 Digital 12xIn, 8xRelay Out #57738 offers twelve inputs ready to use with switching contacts or for processing 24V signals. Seven potential-free changeover contacts and one normally open are available. Model #57738 can be powered over PoE without the need for an external power supply.
