PLC Module – Weight Modules

Hardy PLC Module – Weight ModulesThe Hardy line of general-purpose PLC weight modules are used in a wide variety of applications such as Batching/Blending, Filling/Dispensing, Check Weighing, Level by Weight, Force measurement, Rate Control and Rate Monitoring to name a few. They are available in single (-WS) or dual (-2WS) configurations. They transfer clean; accurate weight data directly to the PLC/PAC which uses its rack I/O for application control. The RS Logix modules include Add-On-Profiles for ease of integration.

HI 1769-WS and HI 1769-2WS

Hardy HI 1769-WS and HI 1769-2WS

HI 1769-WS and 1769-2WS CompactLogix® Module

Small size, high performance!

Hardy HI 1769-WS and -2WS are single channel PLC-style weigh scale  modules for use with the Allen-Bradley MicroLogix® 1500 and CompactLogix® controllers.

Super Easy Integration

  • Free Add-On-Profiles
  • Free Faceplates for HMIs
  • Direct Back-plane Connectivity

The HI 1769-WS and -2WS reads and conditions weight and diagnostic data from strain gauge load sensors or load cells up to one hundred times per second and communicates this data over the I/O chassis backplane to the PLC processor. The HI 1769-WS module reduces installation costs, as it needs no external stand-alone scale instrument with a wired communications link to the PLC.

High resolution enables the module to tolerate large dead loads and over sizing of the load sensors, while retaining a high level of usable resolution. 

The WS module supplies 5 volts of DC excitation to drive up to four 350-ohm load sensors or load cells associated with a single scale. The 2WS supports up to eight 350-ohm load cells with two scales.  Both will support additional load cells with an external power supply.

The HI 1769-WS incorporates Hardy Process Toolbox core features of WAVERSAVER®, C2® electronic calibration INTEGRATED TECHNICIAN® (IT).

Rockwell Add-On-Profile (AOP)

Quickly and easily configure the HI 1769-WS for your application through PLC software on a PC.  A face plate makes the modules incredibly easy to use with common weighing functions built into the faceplate.

Easy 8

Hardy Easy 8™ Micro800 Weigh Scale Module

Easy 8™ Micro800 Weigh Scale Module

Hardy Process Solutions EASY 8™ Weigh Scale Module (HI 2080WS) is for the Allen-Bradley® Micro800™ programmable controller. This low cost solution is designed to provide “just enough“ functionality that strikes a balance between price, quality of weight reading and Hardy’s reputation for high quality process measurement products.

The EASY 8 is a single channel plug-in module that reads, conditions, and digitizes load cell sensor and strain gage signals commonly found in process weighing applications. It is an ideal plug-in solution for stand-alone, small machine applications in which weighing and weight-based controls are critical functions of the equipment.

The Hardy EASY 8 is a powerful weight processing module that calculates and digitizes net and gross weight data from Hardy load cells (or industry standard load cells) and sends this data directly to the backplane Allen-Bradley® Micro800™ PLC.

Featuring vibration immunity based on Hardy’s WAVERSAVER® technology, the EASY 8 module is delivered with SELECTABLE FILTERING that ignores vibration and mechanical noise typically found in machine and factory environments. By ignoring the effects of unwanted vibration or system noise – scale settling time is reduced and the output speed of stable Gross and Net weight readings is dramatically increased.

Rockwell Automation has produced a video showing the Hardy HI Easy 8 (2080-WS) and the Micro800 in a shrink wrapping application where pallets can be weighed after they are shirinkwrapped.  See the Video

Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy-to-maintain and save you time, money, raw materials and/or finished product.

HI 1756-WS and HI 1756-2WS

Hardy HI 1756-WS and HI 1756-2WS

Single and Dual ControlLogix® Weigh Scale Modules

Hardy’s single (HI 1756-WS) and dual (HI-1756-2WS) are weigh scale modules that mount directly into an Allen-Bradley ControlLogix® PLC Chassis. They read weight and diagnostic data from one set or two separate sets of strain gauge load sensors or load cells and communicate this data over the I/O chassis backplane to the ControlLogix Processor.

Super Easy Integration

  • Free Add-On-Profiles
  • Free Faceplates for HMIs
  • Direct Back-plane Connectivity

The HI 1756-WS and 2WS condition and digitize the weight signals and then transmit the selectable Gross, Net and/or Rate-of-Change data to the PLC processor. High data resolution allow the modules to tolerate large dead loads and over sizing of the load sensors while retaining a high level of usable resolution.

The modules supply 5 volts of DC excitation to drive up to four 350 ohm load sensors or load cells associated with a single scale (four additional for the 2WS scale). They will support additional load cells with an external power supply.

The HI 1756-WS and 2WS both support the use of the producer/consumer technology in the ControlLogix® system to transmit data. This type of communications is an intelligent data exchange in the system where the module produces data without having to be polled.

Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy-to-maintain and save you time, money, raw materials and/or finished product.

Rockwell Add-On-Profile (AOP)

Quickly and easily configure the HI 1756-WS or 2WS for your application through PLC software on a PC.  An HMI face plate makes the modules incredibly easy to use with common weighing functions built in.
