Description

The Allen-Bradley 1756-2WS is a specialized dual-channel weigh scale module engineered for the ControlLogix platform. Developed in partnership with Hardy Process Solutions, this module enables the direct integration of industrial load cells and weigh scale platforms into the ControlLogix backplane. By providing two independent scale channels, the 1756-2WS enhances system density, allowing for the simultaneous monitoring of two separate vessels, silos, or platforms while minimizing the required rack space.

Features

  • Dual-Channel Architecture: Independent processing for two separate scale platforms within a single ControlLogix slot.
  • High-Resolution Conversion: Integrated high-resolution analog-to-digital converters for laboratory-grade weight data.
  • Load Cell Compatibility: Supports up to eight 350-ohm Full Wheatstone Bridge strain gauge sensors, with a capacity of four load cells per channel.
  • Advanced Filtering: Utilizes Hardy's proprietary WAVERSAVER technology to electronically suppress mechanical and structural noise from plant machinery, mixers, or piping shock.
  • Direct Data Access: Provides weight data directly to the controller tag database for seamless integration into automation logic.

Applications

This module is ideal for high-precision industrial weighing applications, including batching, blending, inventory management, and force measurement. It is commonly deployed in chemical processing, food and beverage manufacturing, and material handling systems where stable, noise-free weight data is critical for process control.

Installation Guidelines

  • Power Down: Always disconnect backplane power before inserting or removing the module from the chassis.
  • Grounding: Ensure the ControlLogix chassis is properly grounded according to local electrical codes to minimize EMI/RFI interference.
  • Wiring: Use shielded, twisted-pair cabling for load cell connections to maintain signal integrity. Route signal cables away from high-voltage AC power lines.
  • Environment: Install in an environment that does not exceed the specified operating temperature and altitude limits (1000 meters).
  • Handling: Use standard ESD precautions when handling the module to prevent damage to sensitive internal circuitry.

FAQ

Q: Can this module be used with any load cell?
A: The 1756-2WS is designed for use with 350-ohm Full Wheatstone Bridge strain gauge load cells. Please verify your sensor specifications match these requirements.

Q: Does this module require external power for the load cells?
A: No, the module provides the necessary excitation voltage to the load cells directly. It draws its power from the ControlLogix backplane.
