Features and Benefits

  • Includes Instrument Manager Software which provides: monitoring and direct management of individual load cells. (Does NOT display individual load values).
  • Digital Equalization.
  • 4 channel load distribution signaling with archive backups.
  • Automatic Diagnostics can make comparisons between recorded values and display an alert if significant variations between the values are detected.
  • Event Log archives data in chronological order of the last 50 events related to calibrations, zero settings, errors and equalizations.
  • Connection to:
    • PLC via analog output or fieldbus.
    • PC/PLC via RS485 (Up to 99 instruments with line repeaters, up to 32 without line repeaters).
    • Instrument Manager PC Software can connect to one INF4 at a time via RS485.
    • Remote display via RS485.
    • Excitation Remote Sense.
    • 16 load cells in parallel.
  • Available Fieldbus Protocol Options.
  • Digital Filter to reduce the effects of weight oscillationTheoretical calibration and real calibration with the possibility of weight linearizion up to 5 points.
  • Tare weight zero setting.
  • Automatic zero setting at power on.
  • Semi-automatic tare (net/gross weight) and predetermined tare
  • Semi-automatic zero.
  • Direct connection between RS485 and RS232 without converter.

Standard Configuration

  • RS485 serial port for communication via Modbus RTU protocol, ASCII bidirectional or continuous one way transmission.
  • 3 relay logic outputs controlled by setpoint values or via protocols.
  • 2 optoisolated PNP logic inputs: status reading via serial communication protocols.
  • 4 load cell dedicated input SUMMED output from up to 4 load cells.
  • Back panel mounting on Omega/DIN rail or front panel (except PROFIBUS DP version) with fixing kit included (panel drilling template 23×96 mm; panel thickness 2.5 mm).
  • Dimensions: 26x115x120 mm.
  • Six-digit red LED semi-alphanumeric display (8 mm height), 7 segment.
  • Six indicator LED.
  • Four buttons for system calibration.
  • Extractable screw terminal boards.

Basic Information

  • It is recommended that the power supply negative pole be grounded.
  • It is possible to supply up to 16 350 ohm load cells.
  • For 4-wire load cells, make a jumper between EX- and REF- and between EX+ and REF+. Connect terminal “- SUPPLY” to the RS485 common of the connected instruments in the event that these receive alternating current input or that they have an optically isolated RS485.
  • In case of an RS485 network with several devices, it is recommended to activate the 120 ohm termination resistance on the two devices located at the ends of the network.

Wiring Diagram

In case of difficulty connecting all the reference wires of the installed load cells, simply connect those of the load cell located at the average distance from the instrument. The reference wires not used must be individually isolated.

USE OF 4-WIRE LOAD CELLS: if all the load cells used are 4-wire, make a jumper between -EX (26) and -REF (22) and between +EX (25) and +REF (21).
