A&D's new indicator, the AD-4402 is designed for batching operations and can also be incorporated into systems using Field Bus as CC-Link, DeviceNet and PROFIBUS.

AD-4402 has almost all the functions, user-friendly operating procedures and software you need for weighing system.

Features

  • Large and easy to use blue Vacuum Fluorescent Display (VFD)
  • Uses a ten key pad and function buttons that are designed for ease of operation and understanding
  • The main display has 108, 5mm characters and shows that values and error comments
  • The main display has a 7-digit VFD with 18mm tall characters
  • Pre-programmed with multiple sequences and functions for filling machines, simple mixing machines and other applications
  • Stores 100 data for raw materials and 100 data for recipe codes
  • RS-485 Serial Interface 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 to 135mm
  • With the proper optional interface, the AD-4402 is compatible with CC-Link, DeviceNet, PROFIBUS
