These compact devices include everything you need to connect digital input and output ports of industrial 24V technology to the network. In many cases, it is even possible to manage without additional relays. The wide input voltage range also enables operation at 12 V.

Like the configuration of the device, the reading and/or control of the input/output ports is done via a Web browser. Beyond this, access facilities via TCP/UDP sockets, OPC, SNMP or via e-mail are also available.

Possible applications

Remote monitoring, automation technology, home and building technology and building visualization, process monitoring, photoelectric beam control, gate control, light barrier control, machine data acquisition, customer counting, fault indicators and much more.
