Web-IO® Analog

Analog in- and outputs in the network

With the Web-IO you use the network to access analog current and voltage signals. Depending on the model the devices monitor and set 0/4-20mA or 0-10V unit signals per DIN IEC 60381-1 and -2. Box-2-Box mode transmits the detected signal levels to remote locations. Various data protocols also enable uncomplicated incorporation into SCADA, MES and IoT systems as well as applications from Industry 4.0.

The Web-IO Analog lets you access analog current and voltage signals over Ethernet. Depending on the model the devices monitor and set 0/4-20mA or 0-10V signals per DIN IEC 60381-1 And -2.


  • Detect and monitor
    The Web-IO Analog measures, stores and monitors the signal levels present on the inputs. Configurable actions monitor them and can for example trigger issuing of an e-mail notification.
  • Signal transmission between different locations
    In Box-2-Box mode the in- and outputs on two devices are represented alternately.
  • Integration into process control systems, MES and Industry 4.0.
    via MQTT, Modbus/TCP, OPC and SNMP, other network protocols and programming interfaces.
