1746-WS | Allen-Bradley Weigh Scale Module
The Allen-Bradley 1746-WS is a microprocessor-based weigh scale I/O module designed for integration into the SLC 500 system platform. It processes signals directly from strain-gauge load cells, performing high-speed analog-to-digital conversion and digital filtering to deliver accurate weight and force measurements directly to the 1746 chassis backplane.
Signal Processing and Operations
The digital printed wiring assembly (PWA) architecture enables standalone signal processing, offloading scale calibration, tare calculations, and weight data formatting from the main SLC 500 processor. The module incorporates local solid-state outputs rated at 10 mA per line, allowing direct triggering of fast-acting control elements such as valves, feeders, or alarms based on pre-programmed weight thresholds.
Backplane Integration and Installation
Engineered to occupy a single slot in any standard 1746 I/O chassis, the 1746-WS communicates via the internal backplane logic for rapid data updates. Its dedicated microprocessing capabilities make it suitable for industrial batching, tank weighing, hopper fill control, and inline scale systems requiring low latency and reliable strain-gauge signal conditioning.
