Built with robust electrical components, it integrates directly into SLC chassis slots and communicates with RIO adapters through Belden 9463 cabling. It supports multiple baud rates and long cable spans, making it suitable for applications requiring extended-distance communication. The module is compatible with SLC 5/02 through 5/05 processors and incorporates DIP switch configuration for flexible network setup.

Key Features:

  • Single RIO Port: Provides a dedicated three-pin interface for remote I/O communication using approved cabling.
  • Long-Distance Capability: Supports cable runs up to 3048 meters for widespread device placement in industrial layouts.
  • Multi-Baud Operation: Offers selectable data rates including 57.6 Kbaud and 230.4 Kbaud for adaptable network performance.
  • SLC 500 Compatibility: Designed for use with SLC 5/02, 5/03, 5/04, and 5/05 processor modules.
  • High Backplane Support: Operates with 600 mA at 5 VDC and 90 mA at 24 VDC to ensure stable controller integration.
  • Environmental Durability: Functions reliably across 0–60°C with wide humidity tolerance for industrial environments.
  • Daisy-Chain Topology: Supports multiple RIO devices with proper termination for efficient network organization.

The 1747-SN delivers the reliability and precision required for robust remote I/O communication within SLC 500 control systems.

Frequently Asked Questions about 1747-SN
Question: What is the Allen-Bradley 1747-SN used for?
Date Update:16/06/2025
Answer:

The Allen-Bradley 1747-SN is a Remote I/O (RIO) Scanner Module designed for use within SLC 500 systems. It enables high-speed communication between SLC processors, Human Machine Interfaces (HMI), PanelView displays, and other RIO-enabled devices. Operating over a Belden 9463 cable, the module facilitates real-time I/O data transfer, diagnostics, and control messaging in distributed automation networks. It is often deployed in applications that require modular, scalable communication across multiple industrial control components. With a single RIO port, it simplifies network structure while supporting robust and reliable data exchange.

Question: Which devices are compatible with the 1747-SN?
Date Update:16/06/2025
Answer:

The 1747-SN is built for interoperability within the Allen-Bradley ecosystem and beyond:

  • Compatible with SLC 5/02, 5/03, 5/04, and 5/05 processors.
  • Communicates with PanelView terminals, remote I/O adapters, and message displays.
  • Interfaces with third-party RIO adapters, protocol converters, and gateways.
  • Fully supported in 30-slot chassis systems.

This broad compatibility ensures seamless integration into a variety of legacy and modern industrial systems.

Question: How is the communication cable configured for this module?
Date Update:16/06/2025
Answer:

The communication cable setup follows strict industrial standards:

  • Uses Belden 9463 twisted-shielded pair cable.
  • Supports up to 3048 meters (10,000 feet) at 57.6 Kbaud.
  • Requires daisy-chain topology with 82-ohm terminators at both ends.
  • Baud rate and topology affect cable length and number of devices.

Proper termination and shielding are essential for signal integrity across long distances.

Question: How to wire 1747-SN?
Date Update:16/06/2025
Answer:

Wiring the 1747-SN requires attention to cable type and topology:

  • Use Belden 9463 cable or equivalent twisted shielded pair.
  • Follow daisy-chain topology, connecting one device after another.
  • Terminate both ends with 82-ohm, ½ watt resistors.
  • Connect the cable to the 3-pin terminal on the module.
  • Ground the shield at one point only to avoid noise loops.

Correct wiring ensures stable, interference-free communication across all RIO devices.

Question: Is the 1747-SN still in production?
Date Update:16/06/2025
Answer:

Yes, the Allen-Bradley 1747-SN is still in production and officially supported by Rockwell Automation. It remains part of the SLC 500 ecosystem, although new systems are increasingly built with CompactLogix or ControlLogix.
