Web-IO® Digital 24V

24V switching signals in the network

The Web-IO Digital offers access to switching signals over the network. Signals up to 30V are supported, or higher voltages using coupling relays. The states of the inputs are detected, evaluated and monitored using configurable actions. For example, you can send email alarms or switch outputs when an input changes its state.
