Product Overview

The Allen-Bradley 1769-WS (developed by Hardy Process Solutions for Rockwell Automation) provides high-precision weight measurement directly within the CompactLogix backplane. This single-channel module interfaces with standard strain-gauge load cells, converting millivolt signals into usable weight data for batching, filling, and material handling. By eliminating external transmitters, the 1769-WS reduces signal noise and simplifies cabinet architecture. We supply this module in 100% Brand New original condition, ensuring laboratory-grade accuracy in your industrial process.

Technical Specifications

The 1769-WS utilizes a high-resolution 24-bit A/D converter to resolve minute changes in tension or compression across the load cell bridge.

Engineering Advantages

The 1769-WS solves traditional weighing challenges by integrating signal conditioning and calibration directly into the PLC environment.

Direct Load Cell Integration: This module replaces the need for external scale indicators and 4-20mA transmitters. Direct integration reduces the number of components in the signal chain, which minimizes error sources and simplifies the I/O configuration in Studio 5000.
WAVERSAVER® Vibration Rejection: Utilizing advanced filtering, the module ignores plant-floor vibrations caused by mixers, conveyors, and nearby machinery. This technology ensures stable weight readings even while mechanical equipment operates at full capacity.
High-Precision 24-Bit Conversion: The ultra-high resolution allows the system to detect extremely small weight increments. This precision proves vital for chemical batching and pharmaceutical packaging where strict tolerance levels are mandatory.
Remote Software Calibration: Engineers calibrate the scale through the controller software without needing to adjust physical potentiometers. This allows for rapid re-zeroing and span adjustments from the HMI, reducing maintenance downtime.
Hazardous Area Compatibility: With Class I Div 2 certification, the 1769-WS operates safely in areas where hazardous vapors or gases exist, making it a standard choice for oil, gas, and chemical processing plants.

FAQs

Can the 1769-WS power multiple load cells?

Yes. The 5V DC excitation output provides enough current to power up to four 350 $\Omega$ load cells connected in parallel, allowing for the weighing of large tanks or platforms supported by four structural legs.
Does this module support C2® electronic calibration?

While the 1769-WS supports advanced software calibration, verify your specific firmware revision for C2® compatibility, which allows for calibration without the use of physical test weights.
Is the 1769-WS compatible with all CompactLogix processors?

It integrates seamlessly with all 1769-series CompactLogix controllers and the MicroLogix 1500. It also functions as remote I/O when used with a 1769-AENTR Ethernet adapter.
What is the maximum cable distance between the load cell and the module?

For optimal 24-bit accuracy, keep the load cell cable within 250 feet (75 meters) and utilize high-quality shielded 6-wire cable to compensate for voltage drops in the excitation lines.
