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.

Analog connection:

• Two channels, selectably configurable as:

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

Connectivity:

• Monitor analog measurements and processes from a browser
• Alarm and reporting function:
  • E-mail for alarm or reporting functions
  • SNMP polling / alarm traps
  • Up to 8 alarm messages can be configured
• Box2Box mode tunnels analog signals between two devices
• Set analog values via socket command, direct entry or slider
  
  
• Active current input 0/4-20mA
• Interactive display, custom scalable
• Dynamic integration into other Web sites:
• Direct access to current measurement values via AJAX, JavaScript and Java applet
• Additional software interfaces for incorporating into your systems/databases:
  • 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: 15s, 30s, 1m, 5m, 15m, 60m
• 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
