Specification

The 1769-SDN ALLEN-BRADLEY is a robust DeviceNet scanner module designed for the CompactLogix platform, enabling efficient control and monitoring of DeviceNet networks. This module acts as a master device, managing up to 63 slave nodes with deterministic I/O updates, making it ideal for distributed automation systems in manufacturing, packaging, and material handling. It supports three baud rates (125 kbps, 250 kbps, 500 kbps) and features advanced diagnostics for fault detection and network optimization. The 1769-SDN integrates directly into the CompactLogix backplane, reducing wiring complexity and enhancing system reliability. Below are the detailed technical specifications for this module.
