AD-4401A

Product catalog summary

Overview: The AD-4401A is a versatile weighing indicator suitable for various weighing systems, offering precise control and multiple application functions. It supports both Modbus-RTU and Modbus-TCP communication protocols, allowing easy integration with PLCs and HMIs.

Key Features:

Batching and Loss-in-Weight Measuring: Provides precise control with timers and settings for dispense control and supplementary fill.
Modbus Communication: Options include RS-485 (Modbus-RTU) and Ethernet (Modbus-TCP), facilitating easy function setting and data collection.
Digital Span Calibration: Allows calibration without actual weights by inputting specified load cell voltage.
Automatic Weight Accumulation: Accumulates net weight automatically, storing data in non-volatile memory.
Supplementary Flow: Engages drizzle flow to reach target weight, preventing shortages.

Weighing Modes:

Batch Weighing Mode: Supports four types of weighing and batching modes with a high sampling rate, suitable for hopper and packer scales.
Comparator Mode: Offers four weighing modes for sorting products by weight, with signals for five checkweighing levels.

External I/O and Options:

Standard control I/O includes 6 inputs and 8 outputs.
Options for BCD Output, RS-422/485, RS-232C, and Ethernet connectivity.
Analog output available for transmitting weight data to devices.

Design and Compatibility:

Maintains size, color, and installation method of the previous model, AD-4401, ensuring compatibility with existing devices.
Features a high-performance digital filter for environments with vibrations, reducing the need for mechanical countermeasures.

Display and Operation:

Equipped with a large main and sub display with bright VFD displays for quick data confirmation.
Operation and setting key switch designed for ease of use.

Specifications:

Analog Unit: Input sensitivity over 0.3μV/d, zero adjustment range 0mV to 20mV, and load cell excitation voltage DC10V±5%.
Digital Unit: VFD display with main and sub displays, status indicators, and a sampling rate of 100 times per second.
General Specifications: Power supply voltage AC100 to 240V, operating temperature -10˚C to 40˚C, and dimensions 144(W) x 72(H) x 197(D) mm.

Conclusion: The AD-4401A is a reliable and accurate weighing indicator with advanced features for diverse applications, ensuring high performance even in challenging environments.

Complete with measuring sequence and transmission functions. Advanced system for hoppers, checkweighers and platform scales is now even more accurate! Easily replaceable G The size, color, method of operation and installing to a control panel of the AD-4401A remains the same as the AD-4401. G Interface connectors retain compatibility so even when updating from AD-4401 to AD-4401A previously connected devices can continue to be used without changing any connectors. G Functions have been added but the default settings remain identical to the AD-4401. The AD-4401A incorporates a multitude of application...
