EtherNet/IP Deterministic Networks and I/O Density Scaling
The 1769-2WS integrates measurement acquisition functions into Allen-Bradley CompactLogix architectures through backplane communication. The module processes low-level millivolt signals from strain gauge and load cell devices while providing excitation voltage for connected transducers.
The module follows industrial control I/O density scaling principles by adding dedicated weighing channels without external signal conversion hardware. Its 100 updates per second conversion rate supports continuous measurement processing within controller-based applications.

Field Installation Guidelines
Install the 1769-2WS module in a compatible CompactLogix or MicroLogix 1500 I/O assembly following the controller platform installation requirements.
Connect load cell and strain gauge wiring using suitable shielded instrumentation cable. Route low-level millivolt signal wiring separately from power conductors and high-current switching circuits to reduce electrical interference.
Terminate cable shields according to the system grounding design. Verify excitation polarity, signal polarity, and sensor wiring before applying system power. Confirm module configuration parameters match the connected transducer type and weighing mode.
