Allen-Bradley 1769-ADN DeviceNet Adapter

Description

The Allen-Bradley 1769-ADN DeviceNet Adapter is a CompactLogix I/O module designed to connect simple industrial devices such as sensors and actuators to factory floor controllers like PLCs and computers. Built on the Common Industrial Protocol (CIP), it provides core functions including device control, data collection, and configuration, enabling direct integration of low-level equipment with higher-level control systems without intermediate I/O modules. Key technical specifications include communication rates of 125 Kbps at 500 meters, 250 Kbps at 250 meters, and 500 Kbps at 100 meters, support for up to 30 I/O nodes, and current draw of 450 mA (A series) or 500 mA (B series) at 5 volts DC. The module measures 4.65 x 1.97 x 3.43 inches. For installation, it fits into slots 3-8 of a CompactLogix chassis, uses shielded twisted pair wiring for connections, requires 120 ohm terminal resistors at the network ends, and connects to a 24 volts DC power supply (200 mA) via a removable terminal block. Configuration is completed through RSLogix 5000 software, including setting device names, matching communication rates, importing EDS files, and creating scan lists to optimize data transfer and system monitoring.
