• AND Weighing Indicator AD-4402

    Multifunction Weighing Indicator with Field Bus Support

    The AD-4402 combines a small body with a large display and excellent weighing sequence functions.
    The AD-4402 can be used with various factory devices with its support for field bus (CC-Link, DeviceNet, PROFIBUS), Modbus, serial, parallel, analog output and relay output.


    • Large Vacuum Fluorescent Display (VFD) with 18mm characters on main display
    • Sub display shows weight, raw material, setpoint, cumulative value, code name, and error message, etc. on the same screen.
    • Waterproof front panel (IP-65 compliant)

    Weighing Functions:

    • Preprogrammed with normal-batching and loss-in-weight sequences
    • Batch-time/discharge-time monitoring and supplementary flow function
    • Mixing function – one unit can mix multiple materials
    • Sequence functions for filling and mixing
    • High-speed sampling at 100 times/sec enables swift response to weight changes
    • Memory function
    • Stores 100 data values of both raw materials and recipe codes

    External I/O:

    • Configurable Control I/O: 11 Input nodes, 11 Output nodes
    • Standard RS-485, Current Loop Output (for connection to A&D peripheral devices)
    • Modbus-RTU
    • Optional Items
      RS-232C, RS-422/485, Relay Output, Parallel BCD Output, Analog Output (4-20mA)
    • Field bus Can connect to CC-Link, DeviceNet, PROFIBUS (optional)

    Digital Calibration Function
    Supports all power sources

    • AC100 to 240V (switching-mode power supply) DC 24V model also available (AD-4402D)
