Allen-Bradley 1756-WS Weigh Scale Module

The Allen-Bradley 1756-WS is a specialized module for integrating weight scales into Allen-Bradley ControlLogix systems. This single-channel module processes data from strain gauge sensors or load cells and transfers it to the ControlLogix processor via the chassis backplane.

Key Features and Specifications

• Single-Channel: Processes data from one weigh scale.
• Strain Gauge Compatibility: Supports up to four 350 Ohm full Wheatstone bridge strain gauge load sensors/cells.
• 5 Volt Excitation: Provides necessary power for strain gauges.
• C2® Electronic Calibration: Ensures precise calibration capabilities.
• ControlLogix Integration: Seamlessly integrates with the ControlLogix platform.
• Producer/Consumer Technology: Facilitates efficient data transfer within the ControlLogix system.
• Diagnostic Data: Supplies detailed information about the module and connected sensors.

Applications

The 1756-WS module is used in various industries for:

• Process Control: Monitoring and controlling weight-based processes.
• Packaging: Weighing and packaging products.
