AND AD-4402 weighing Indicator



Kitoma Indonesia : AND AD-4402 weighing Indicator


Multi-function weighing Indicator

Performs many operations, from batch weighing to field bus networking applications

The AD-4402 is designed for batching operations and can also be incorporated into system using Field Bus such as CC-Link, DeviceNet and PROFIBUS

AD-4402 has almost all the function, user friendly operatiing procedures and software you need for your weighing system.

Hopper gate control is done by forecast control mode with 1msec high speed response
Incorporates Recipe and Mixing modes
Select from 50+ function for each of the 11 Control Inputs and 11 Control Ouput
Meets Fieldbus requirements by employing CC-Link, DeviceNet and PROFIBUS


  • Large and easy to see blue Vacuum Fluorescent Display (VFD).
  • Uses a ten - key pad and function button that are designed for ease of operation and understanding.
  • The main display has a 7 - digit VFD with 18mm tall characters.
  • The sub display has a total of 54 5mm - tall dot matrix characters and displays the values and error comments.
  • Pre-programmed with multiple sequences and functions for filling machines, simple mixing machines and a weight-checker and other applications.
  • Stores 100 data for raw materials and 100 data for mixing codes.
  • RS-485 Serial Output (Current Loop) standard feature allows you to link up to 32 units to the display and supports the Modbus function.
  • The Monitor Function shows each operating interface and provides a confirmation on the display.
  • The compact body meets DIN requirements, while minimizing the depth of the indicator to135mm.
  • With the proper optional interface, the AD-4402 is compatible with CC-Link, Device Net, PROFIBUS.
  • Standard Modbus function available.
  • 100 times/sec. High speed sampling.
  • High display resolution to 16,000 counts.
  • Up to 1 million counts of A/D resolution.



AD-4402 can be incorporated in various applications that integrate complex system, thereby facilitating a wide variety of sequence, such as basic filling/discharge, recipe, mixing, compensation and preliminary sequences.
