Product Overview

The Allen-Bradley 1769-ADN belongs to the CompactLogix family of I/O modules. This DeviceNet adapter connects actuators and sensors directly to controllers without I/O modules. The Allen-Bradley 1769-ADN uses the Common Industrial Protocol (CIP) for control and data collection. You get a maximum of 30 I/O nodes on the network. The module supports DIN rail or panel mounting for flexible installation. The Allen-Bradley 1769-ADN reduces start-up time and wiring compared to hard-wired systems.
