Allen Bradley 1746-WS — Detailed Technical Overview
1. Product Introduction
The Allen Bradley 1746-WS is a weighing scale module designed for integration within the SLC 500 PLC platform. It is a specialized intelligent module used for industrial weighing and force measurement applications, combining signal acquisition, processing, and control in a single unit.
Unlike standard I/O modules, this module contains an internal microprocessor that allows it to directly process load cell signals without requiring external signal conditioners. It connects to the PLC backplane and operates as an independent weighing controller while still exchanging data with the main processor.
The module supports functions such as gross weight, net weight, and rate-of-change measurement. It is commonly used in systems where precise weight monitoring and control are required, such as batching, filling, and dosing operations.
