Allen-Bradley 1769-SDN DeviceNet Scanner Module

Overview

The Allen-Bradley 1769-SDN Series B is a CompactLogix DeviceNet Scanner communication module that interfaces between DeviceNet devices and programmable controllers. This module acts as a bridge for data exchange with slave devices, peer-to-peer messaging, and program upload/download operations across a DeviceNet network. Compatible with both CompactLogix 1769 and MicroLogix 1500 systems, it delivers reliable industrial communication in a compact form factor.

Key Features

DeviceNet scanner interface for slave device I/O read/write and peer messaging
Selectable baud rates: 125K, 250K, and 500K bits/second for network flexibility
DIN rail or panel mount configuration for flexible installation
Compact design (118×87×35 mm) with low power draw (440 mA @ 5V DC)
Program upload/download capability to 1764-LRP-based MicroLogix 1500 controllers across DeviceNet
No external power supply required; draws power from backplane
