Web-IO 4.0 Digital 4xIn/Out

Switch, monitor and count ...

With the Web-IO 4.0 Digital switching signals can be controlled, detected and monitored over TCP/IP-Ethernet. The 4 switching channels can be used as input or output. Numerous Web and network services are available for reporting changes on the inputs and outputs - including directly in the browser. Using protocols such as OPC UA, MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.

Properties

Switching signals:

  • 4 channels:
    • Can be used optionally as inputs or outputs
    • 24V technology
    • Switching currents up to 500mA
    • 32-bit pulse counter

Connectivity:

  • Intuitive Web interface for simpler operation
    • Select between German or English
    • Switching the outputs directly from the Web interface
    • Adaptation for smartphone
    • HTTP and HTTPS
  • Current Industry 4.0 protocols:
    • OPC UA, REST and MQTT support
    • AMQP on request

  • Alarm and reporting functions:
    • Email for alarm sending or as status report
    • SNMP polling / alarm traps V1 V2 V3
    • Switching your outputs in alarm situations
    • Switching the outputs on another Web-IO
    • HTTP requests for controlling third-party devices
    • Up to 30 actions can be configured
  • Dynamic integration into other Web sites:
    • Direct access to current states via HTTP requests, AJAX and JavaScript
  • Additional software interfaces for incorporating into your systems/databases:
    • OPC UA, OPC DA
    • Modbus TCP
    • Syslog, SNMP V1 V2 V3
    • TCP and UDP sockets, client and server
    • HTTP, HTTPS, AJAX
    • FTP (data logging)
  • Internal clock
    • Time synchronization via time server calibration
    • Battery-backed device clock
  • Possible applications:
    • Remote monitoring and fault messaging
    • Cross-location switching
    • House and building automation
    • Process monitoring and visualization
    • Light, gate and cabinet control
    • Machine Data Collection (MDC)
