Product Name: AD-4402 Weighing Indicator
Brand: A&D
Type: Multi-Function Weighing Indicator
Model:
AD-4402
Large and easy to see 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 a 7-digit VFD with
18mm tall characters.
●The subdisplay has 108, 5mm tall
characters and shows the values and error
comments.
●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 to135mm.
●With the proper optional interface, the
AD-4402 is compatible with CC-Link,
DeviceNet, PROFIBUS.
AD-4402 can be incorporated in various applications that
integrate complex systems, thereby facilitating a wide variety of
sequences, such as basic filling/discharge, recipe, mixing,
compensation and preliminary sequences.
★Sequential weighing mode
The sequential weighing mode directly outputs control
signals such as supply, discharge, preliminary-fullmedium-dribble flow, recipe and mixing materials and
nozzle control without PLC.
★Interactive messages
Messages that assist current operations are shown
on the display and allow anyone to operate the
AD-4402 without an instruction manual. Just follow
the interactive setting and operating procedures on
the display. Sometimes mistakes happen. When they
do, a message is displayed so you can recognize the
situation and take corrective steps.
★Digital Span and Gravity Acceleration
Compensation
When you cannot use an actual calibration weight due
to location, just input the load cell rated output voltage
for zero point and full capacity calibration. After
moving the calibrated weighing system, recalibrate it
by inputting the local gravity acceleration value.
★Calibrated A/D board
The A/D board is calibrated before shipment and
guaranteed to 1/500 accuracy. You can quickly
replace the A/D board if there is a malfunction.
★Safety check function
This function is used to stop the sequence when an
error or an emergency occurs. When the safety
function is used, an error code is displayed and an
error signal is output automatically to the PLC to stop
the system. Up to eight emergency overrides can be
installed.
★11 Control Inputs/11 Control Outputs
50+ functions (such as Full Flow, Over, Under,
Discharge Bin, Net Display, etc.) for each of the 11
Control Inputs and 11 Control Outputs, depending on
the weighing system.
★Standard RS-485
32 indicators can be hooked up to the PLC
(programmable logic controller), a PC (personal computer)
or other equipment that supports Modbus.
This is useful for control commands input and
recalling/updating the code memory.
★Optional Field bus networking interface
boards for CC-Link, DeviceNet or
PROFIBUS
To meet increasing requirements for networking with
field bus systems, there are three bus-interface options
(CC-Link, DeviceNet and PROFIBUS), which can be
hooked up directly to the PLC units. More than two
indicators can be hooked up to the PLC at one time.
