Data sheet:

Web-IO 4.0 Analog 0-20mA

  • Analog-Out 0..20mA

Measure, tunnel, output analog signals...

The combined solution for analog in- or output signals brings your measurements into the network and back to the terminal. Use the Web-IO Analog-In/Out to measure analog signals, tunnel them over the network and output them again as analog signals at a remote location.

Properties

Analog connection:

  • Two channels, selectably configurable as:

    • Current input:
      • Input signal: 0/4..20mA active/passive
    • Current output:
      • Output signal: 0/4..20mA

Connectivity:

  • Intuitive Web interface for simpler configuration
  • Monitor analog measurements and processes from a browser
  • Alarm and reporting function:
    • E-mail for alarm or reporting functions
    • SNMP polling / alarm traps
    • Configure up to 12 alarm messages
  • Box2Box mode tunnels analog signals between two devices
  • Set analog values via socket command or direct entry
  • Active current input 0/4-20mA
  • Interactive display, custom scalable
  • Dynamic integration into other Web sites:
    • Direct access to current measurement values, e.g. JavaScript (AJAX).
  • Current Industry 4.0 protocols:
    • REST and MQTT support
  • Additional software interfaces for incorporating into your systems/databases:
    • SNMPv1, SNMPv2c, SNMPv3
    • OPC server
    • Syslog
    • Sensobase (database integration via ODBC)
    • TCP and UDP sockets, client and server
    • FTP (data logging)
    • Modbus TCP
  • Possible applications:
    • Connect each sensor with 0/4..20mA output and monitor measurements
    • Control analog actuators over the network
    • Network as extension: tunnel analog values via Box2Box mode
    • Direct display of multiple measuring points in the browser via Java applet
    • Logging of measurements via FTP, Excel file, email attachment and internal memory

Data logger:

  • Internal data logger
    • Memory capacity: min. 150 days, max. 99 years
    • Save frequency: 15, 30 sec, 1, 5, 15, 60 min
  • Document measurement data online in the W&T Cloud and access from anywhere in the world
  • Internal clock
    • Time synchronization via time server calibration
    • Battery-backed device clock

Standards & more

  • Supply voltage via Power-over-Ethernet (PoE)
    • Phantom power using data pairs
    • Power over unused wire pairs
    • External power supply is an alternative
  • Conforms to standards both in office and industrial environments:
