The Allen-Bradley 1771-WS is a weigh scale input module designed for the PLC-5 (1771) platform. It provides high-precision measurement of low-level analog signals from load cells and strain-gauge-based weighing systems. With 20-bit resolution and support for advanced data formatting, the module is widely used in industrial weighing applications such as batching, blending, filling, and material handling systems where accurate weight measurement is critical.
Reads and processes low-level analog signals from load cells and weighing sensors.
Converts weight measurements into digital data for PLC processing.
Supports high-precision industrial weighing applications such as batching and filling.
Provides real-time weight monitoring for process control systems.
Interfaces directly with PLC-5 backplane for data communication.
Enables accurate load measurement in industrial automation systems.

High-Precision Weighing Performance
With 20-bit resolution, the 1771-WS delivers highly accurate and stable weight measurements compared with standard analog input modules.
Dedicated Weighing Functionality
Unlike general-purpose analog modules, it is specifically designed for load cell applications, ensuring optimized signal conditioning and improved measurement stability.
Stable Low-Level Signal Processing
Engineered for millivolt-level inputs (0–30 mV DC), it provides reliable handling of weak signals from strain gauge sensors in noisy industrial environments.
Flexible Data Handling
Supports both integer and floating-point formats, allowing seamless integration with different PLC programming and data processing requirements.
No External Power Required
Backplane-powered design simplifies installation and reduces wiring complexity compared with modules requiring external excitation or power supplies.
Seamless PLC-5 Integration
Designed specifically for the 1771 platform, ensuring straightforward installation, configuration, and long-term system compatibility.
Reliable Industrial Performance
Built for continuous operation in demanding environments such as batching, packaging, and material handling systems, ensuring consistent weighing accuracy and system stability.
