Allen-Bradley 1769-2WS Weigh Scale Module

The Allen-Bradley 1769-2WS is a high-performance dual-channel weigh scale module, designed by Hardy Process Solutions. It seamlessly integrates with CompactLogix and MicroLogix 1500 controllers. This module is engineered for precise weight measurements, ideal for applications involving strain gauges, load sensors, or load cells.

Key Features

The 1769-2WS supports a wide input signal range, from -0.3mV to +15.3mV, and provides a stable 5VDC excitation voltage. With an update rate of 100 updates per second, it ensures fast and accurate data processing. This rapid update rate is crucial for applications requiring high-speed weight measurement.

Furthermore, the module accommodates up to eight load cells, allowing it to handle complex weighing setups. This feature enables multi-point weighing, which increases the overall versatility of the system. Additionally, the 1769-2WS offers three distinct weighing modes: Net, Gross, and Rate-of-change. These modes provide flexibility depending on the specific requirements of your application.

Calibration is simplified with two methods: C2 Electronic Calibration and traditional calibration using test weights. This flexibility ensures the module can adapt to various operational needs.
