Description Reviews

The Allen-Bradley 1756-WS is a dedicated weigh scale interface module engineered for the ControlLogix platform. Developed in partnership with Hardy Process Solutions, this module enables the direct integration of industrial load cells and weighing platforms into the ControlLogix backplane. By eliminating the necessity for external weight transmitters or signal conditioners, it streamlines system architecture for critical weighing tasks such as batching, filling, vessel monitoring, and force measurement.

Features

Direct interface for up to four 350-Ohm load cells per channel.
High-speed processing with an update rate of 50 updates per second.
Exceptional measurement precision with a non-linearity rating of 0.0015% of Full Scale.
Seamless integration into the ControlLogix backplane for direct data exchange with the controller.
Robust design for industrial environments with an operating temperature range of 0 to 60 degC.

Applications

The 1756-WS module is optimized for industrial weighing environments requiring high accuracy and repeatability. It is frequently deployed in automated filling lines, material batching systems, inventory vessel monitoring, and various force-sensing industrial applications where real-time weight data is essential for process control.

Installation Guidelines

Ensure the ControlLogix chassis is powered down before inserting or removing the 1756-WS module to prevent electrical damage.
Properly ground the module and use shielded cabling for load cell connections to minimize electromagnetic interference (EMI).
Maintain consistent wire routing, keeping signal cables separated from high-voltage power lines.
Verify that the load cell excitation voltage and impedance requirements align with the module specifications before final connection.
Ensure the module is fully seated in the chassis slot and secured with the retention screws to maintain proper backplane contact.

FAQ

Does the 1756-WS require an external transmitter?

No, the 1756-WS is designed to connect directly to load cells, functioning as a bridge between the physical weight sensor and the ControlLogix backplane without external conditioning hardware.

How many load cells can this module handle?

The 1756-WS supports a single channel input capable of managing up to four 350-Ohm load cells in a parallel configuration.
