Allen-Bradley 1747-SDN SLC 500 DeviceNet Scanner Module

Product Overview

The 1747-SDN is a high-performance DeviceNet Scanner Module designed for the Allen-Bradley SLC 500 platform. It serves as the master communication interface, allowing SLC 5/03, 5/04, and 5/05 processors to control, configure, and collect data from up to 63 DeviceNet-compatible slave devices. This module is essential for integrating motor starters, variable frequency drives (VFDs), sensors, and distributed I/O into a centralized control system. By supporting multiple data exchange modes and providing a transparent "Pass-Through" feature for software configuration, the 1747-SDN significantly reduces system wiring while increasing diagnostic visibility across the industrial network.

Technical Specifications

The 1747-SDN integrates directly into the SLC 500 chassis and manages the DeviceNet physical and data link layers.

Manufacturer: Rockwell Automation / Allen-Bradley
Model Number: 1747-SDN
Module Type: DeviceNet Scanner Module
System Compatibility: SLC 500 Series (SLC 5/03 or higher)
DeviceNet Node Capacity: 63 Slave Nodes (Nodes 0–63, Scanner occupies one)
Communication Rates: 125 k, 250 k, and 500 k baud
Backplane Current Draw: 500 mA at 5V DC
DeviceNet Current Draw: 90 mA at 24V DC (sourced from the network)
I/O Messaging Modes: Polled, Strobe, Cyclic, and Change-of-State (COS)
DeviceNet Power: 11–25V DC (Linear power supply recommended)
Isolation: 500V DC (between DeviceNet and SLC backplane)
Operating Temperature: 0°C to 55°C (32°F to 131°F)
Product Net Weight: 0.17 kg (0.37 lbs)

Key Functional Features

Optimized Network Traffic: Through Change-of-State (COS) and Cyclic I/O modes, the 1747-SDN reduces bandwidth consumption by updating the processor only when data changes or at specific intervals.
DeviceNet Pass-Through: This feature enables a PC connected to the SLC processor to configure DeviceNet nodes directly using RSNetWorx for DeviceNet, eliminating the need for a separate 1770-KFD or USB-CAN adapter.
Status Display: A built-in 2-digit numeric display provides real-time diagnostic codes, identifying specific node failures or network errors (e.g., Code 77 for communication faults) for rapid troubleshooting.
Modular Integration: Compatible with standard SLC 500 I/O racks, allowing for easy expansion and hardware migration in legacy systems.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
