Information About 1771-WS
The 1771-WS Hardy weigh scale module is engineered to provide accurate, stable weight measurement for process automation systems using Allen-Bradley PLC-5 platforms. Designed for installation in the 1771 Universal I/O chassis, it interfaces directly with up to four 350-ohm full Wheatstone bridge load cells for high-precision vessel, hopper, or batching applications. With built-in signal conditioning and excitation voltage, the module eliminates the need for external weight processors and integrates weight data seamlessly into PLC logic. It is widely used in material handling, batching, blending, and industrial weighing processes requiring tightly controlled measurement accuracy.
Key Features:
- Integrated Weight Signal Conditioning: Eliminates the need for external weigh controllers by providing direct PLC-integrated processing of mV-level signals from strain gauge load cells.
- Supports Multiple Load Cells: Accepts up to four 350-ohm load cells wired in parallel, enabling single-vessel weighing applications with uniform load distribution and stable readings.
- High-Sensitivity Input Range: Designed for low-level signals (0–30 mV), allowing the module to interpret fine load variations with precision critical for batching and blending.
- Seamless PLC-5 Integration: Operates within the 1771 Universal I/O architecture, allowing weight values to be used directly in PLC-5 control strategies without additional gateways.
- Built-In 10 V Excitation: Provides regulated excitation voltage to the load cells, ensuring consistent signal quality and eliminating the need for standalone excitation hardware.
- Rugged Industrial Design: Engineered for demanding weighing environments, offering dependable operation in process industries such as food, chemical, material handling, and packaging.
- Single-Vessel Support: Optimized for applications requiring one weighing channel, simplifying installation and improving measurement focus for single-scale systems.
- Reliable Power Requirements: Operates from a stable 5 VDC supply and draws 1.5 A, ensuring consistent measurement performance in legacy PLC-5 installations.
The 1771-WS delivers the reliability and precision required for accurate industrial weighing and seamless PLC-5 process integration.
