CHAPTER 1 GENERAL DESCRIPTION

The AD-4401 is a compact-weighing indicator equipped with high-performance A/D conversion and general-purpose capabilities. It has the
following features.

User-friendly cabinet design
• Small DIN size (panel dimensions: 138+1.0/-0 x 68+0.7/-0 mm) easy to mount in a control cabinet.
• Splash-proof front panel.

High-performance A/D Converter
• High-speed sampling, 100 times/second.
• High resolution, 1/16,000.
• High sensitivity, 0.3 µV/D.

Digital Span Capability
• Capable of calibration by inputting a mV/V value without an actual load.
• Capable of directly reading a load cell output (mV/V), for easy installation and maintenance.
• Replaceable without re-calibrating with an actual load in case of trouble.

Flexible Digital Filter allows installation in unstable environments
• Excellent vibration canceling performance.
• Widely covers from high-speed hopper scales to platform scales.

Two-stage Indicators monitoring Tare, Final, and Accumulated Weight values at any time.

Eight Weighing Modes available for wider applications

Capable of being used in a PLC-free hopper system owing to a complete weighing sequence.
• Built-in discharging sequence
• Monitors loading and discharging times
• Supplementary flow capability

Setpoints can be set using RS-232C/422/485 (Optional) as well as the front panel keys or an external thumbwheel
switch.

Control I/O providing a selection of the input/ output terminal capabilities and is available for any system.

High-speed, high-accuracy hopper scale based on Fuzzy Automatic Free Fall Compensation.
