1769-ADN Allen-Bradley DeviceNet Adapter | CompactLogix Module

1769-ADN Allen-Bradley DeviceNet Adapter Module

Product Insight by Oiltech Controls
The 1769-ADN is a DeviceNet adapter for CompactLogix and MicroLogix 1500. It bridges low-level actuators and sensors to high-level PLC controllers. This module uses the Common Industrial Protocol (CIP) for control, data collection, and configuration. It eliminates the need for separate I/O modules by connecting devices directly to plant-floor controllers. Data transmission occurs on demand, which reduces start-up time and wiring complexity compared to hard-wired systems.
