Solutions for simple weight registration for dosing and batching systems


Applikation area: Dosing, Batching


Up to 30 channnels, fast and stable: the HI 6600-Serie.

Hardy HI6600

The HI 6600 series is a modular system of weight processors that deliver up to 30 channels of fast, stable, high-resolution weight readings to PLCs, PACs and DSCs over a single fieldbus network. Ideal for applications that require more than one channel of weight, such as inventory tank farms, batching systems and multi-head filling machinery; each channel of the HI 6600 processes signals from up to four connected load cells then outputs the entire system’s weight data over EtherNet/IP, Ethernet TCP/IP, Modbus RTU, Modbus TCP/IP or Profibus-DP.

Hardy HI6500 and the new HI6500- XP


HI 6500 series are EtherNet/IP® enabled weight processors with a Rockwell Add-On-Profile. They have a big, bright multi-channel display and deliver fast, high-resolution weight readings. They also feature alternative communication options. Weight
processors are used as front ends to control systems or standalone for all types of general weighing applications. They measure, condition and communicate weight without any need to control.

The new HI6500 XP


The NEW HI 6500-XP Extreme Weight Processor can process and output 660 updates per second of processed (stable) weight with a resolution of 1:30,000. The HI 6500-XP represents the state-of-the-art in processing uniformity and speed. A/D conversion, weight processing and the communications port ALL update at 660 times per second, providing the PLC with the latest processed weight reading every 1.5 milliseconds. Many competitor’s products execute the A/D conversion at one frequency, then process the weight and communications ports at a much slower rate typically 20 to 50Hz, only providing the PLC with an update every 20 to 50 milliseconds. The HI 6500-XP results in better product consistency and product yields while reducing processing time, waste time and materials. It is designed for applications where speed and accuracy are paramount to control and quality, such as batching, blending, filling, dispensing and check weighing.

Hardy HI4050 Prozesswägemodul


Hardy HI4050 Weight controller


This weight controller / weight indicator acts as a front end to a PLC, PC or DCS system for most weighing applications, or as a stand-alone for simple control or weight monitoring. 



Modularity – Configure the HI 4050 weight controller to suit your applications:

  • Specify it with or without a display
  • Choose either AC or DC power
  • Add some Digital I/O
  • Select a communication network: DeviceNet, EtherNet/IP, ControlNet, Allen-Bradley Remote I/O, Profibus, Modbus TCP/IP, or Analog
  • Choose between a panel/remote mount, a DIN rail mount, and a wall mount. With a display, you choose either to panel mount the entire assembly, or to mount the controller housing assembly remotely.

Ease of Installation – Installation is easy, with no special tools or expertise required. Just drill five to nine standard holes in your panel, and attach the front panel keyboard display. There is no rectangular cutout required. The controller housing can be attached to the rear of the panel or remotely up to 100 feet away to a DIN rail. Need to replace an HI 2151/30WC or HI 2110WI? Just drill four holes and plug the HI 4050 controller in. 

Small Footprint – The HI 4050 Series controller is designed to optimize panel space and depth is only 76.2 mm (3 in).

Ease of Set-up – By using its embedded web server, you can access the weight controller remotely to control information, instrument parameters and diagnose problems. Front panel keys and graphic display with simple menus provide quick easy setup with process weight and parameter display.

Accessibility – The embedded EtherNet communications port in the HI 4050 weight controller enables users to easily share data across a production facility, eliminating the time and costs associated with new network wiring. 


The HI 4050 weight controller includes Hardy's core features:


Ethernet/IP, DeviceNet, Modbus TCP, Analog, RIO, Profibus

Hardy HI1769 Rackeinbaumodul

Hardy rack mounting modules for CompactLogixTM or  MicroLogixTM 1500


Hardy's HI1769-WS is a single channel PLC-style weigh scale module for use with the Allen-Bradley MicroLogix® 1500 and CompactLogix® controllers.


The HI 1769-WS reads and conditions weight and diagnostic data from strain gauge load sensors or load cells and communicates this data over the I/O chassis backplane to the MicroLogix® 1500 or CompactLogix® processor.


Available dual channel: HI1769-2WS

Special features

Waversaver Eliminates sorrounding vibrations
IT (Integrated Technician) Integrated tool helps you troubleshoot your weighing system and diagnose problems
C2 Provides quick and easy electronic calibration of a weighing system without the need for heavy test weights

Hardy HI1756 Rackeinbaumodul

HI 1756-nDF ControlLogix® Dispenser/Filler Module


Hardy’s HI 1756-nDF is available as a single slot, single channel (HI 1756-1DF) or dual channel (HI 1756-2DF) Dispenser/Filler module that mounts into an Allen-Bradley® ControlLogix® Chassis. Whether filling or dispensing solids, liquids or gases, the HI 1756-nDF automates the entire process by monitoring, controlling, tuning and maintaining the dispense/fill operation.

With two integrated solid state DC or AC relays per channel, Hardy’s HI 1756-nDF places processing power and complete control right where you need it – at the process, making it a true DCS device.

The module can be inserted and removed under power without disruption of any other modules in the system (racks). This makes it possible to replace a failed module while keeping the rest of the system running. Status indicators are provided on the front of the module for fault status. A status block will provide information to the processor for alarming and troubleshooting (IT).

Waversaver Eliminates sorrounding vibrations
IT (Integrated Technician) Integrated tool helps you troubleshoot your weighing system and diagnose problems
C2 Provides quick and easy electronic calibration of a weighing system without the need for heavy test weights
