As a trusted supplier in the industrial automation sector, Rossonix Co., Limited is proud to offer the Allen-Bradley 1747-SN SLC 500 Remote I/O Scanner Module. With over a decade of experience since our establishment in 2011, we specialize in sourcing and supplying high-reliability components for global automation markets. This module represents a critical link in expanding the control capabilities of the robust SLC 500 platform, allowing engineers to efficiently manage distributed I/O points over extended distances, thereby enhancing system flexibility and reducing wiring complexity.
The Allen-Bradley 1747-SN module serves as the central communication hub, enabling a SLC 5/03, SLC 5/04, or SLC 5/05 processor to connect with one or more 1747-ASB Remote I/O Adapter modules. This architecture is fundamental for building scalable and distributed control systems.
Extended System Reach: Facilitates control of I/O devices located far from the central processor, overcoming physical wiring limitations and simplifying cabinet layout.
High-Speed Deterministic Communication: Utilizes Allen-Bradley's Remote I/O (RIO) link protocol, providing reliable and predictable data exchange critical for real-time control applications.
Scalable Network Architecture: Supports the connection of multiple adapter chassis, allowing for modular system expansion as project needs grow without replacing the core controller.
Seamless Integration: Designed for native integration with the SLC 500 family, ensuring straightforward configuration within the RSLogix 500 programming environment and reducing engineering time.
Robust Industrial Design: Built to withstand typical industrial environments with considerations for electrical noise, vibration, and temperature variations, ensuring long-term reliability.
Key technical specifications and configuration details for the 1747-SN module are summarized below:
| Specification Category | Details |
| Compatible Processors | SLC 5/03 (OS301, OS302), SLC 5/04, SLC294 SLC 5/05 |
| Backplane Current Draw | 0.80A @ 5V DC (typical) |
| Communication Link | Allen-Bradley Remote I/O (RIO) Scanner |
| Maximum Adapter Chassis | Configurable; depends on scanner and system setup |
| Module Slots Required | Occupies one slot in the SLC 500 local chassis |
| Status Indicators | LEDs for communication status, scanner activity, and fault conditions |
| Configuration Method | Via RSLogix 500 programming software |
The primary advantage for your operation is significant cost savings in installation and maintenance. By centralizing control logic while decentralizing I/O points, you reduce long runs of expensive multi-conductor cable, conduit, and associated labor. Furthermore, troubleshooting becomes more efficient as I/O status is clearly communicated back to the central processor. This module empowers you to design cleaner, more organized control panels and spread control elements logically across a factory floor or process area.
Rossonix Co., Limited provides a strong foundation of trust for your procurement. Our operations are backed by ISO9001 and ISO9000 certifications, underscoring our commitment to quality management and reliable supply chain processes. With an annual export value between US$5 Million and US$10 Million and a physical presence through overseas offices, we have the logistical capability to serve your needs efficiently. We ship majorly from ports in Shenzhen, Hong Kong, and Europe, ensuring timely delivery to our widespread main markets across North America, South America, Europe, Asia, Oceania, and the Middle East. Choose the Allen-Bradley 1747-SN from Rossonix to leverage our global experience and ensure you receive a genuine, high-performance component that will form the reliable backbone of your distributed control system for years to come.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of the 1747-SN module?
A1: The 1747-SN acts as a scanner module that allows a SLC 500 series processor to communicate with and control I/O points located in remote chassis via the Remote I/O network, extending the control system's reach.
Q2: Which SLC 500 processors are compatible with the 1747-SN?
A2: It is compatible with the SLC 5/03 (with specific operating system series), SLC 5/04, and SLC 5/05 processors. Compatibility should be verified based on the exact processor model and firmware.
Q3: How many remote I/O adapter chassis can I connect to one 1747-SN scanner?
A3: The maximum number depends on the scanner's configuration and the overall system scan time constraints. It is configurable within the RSLogix 500 software, and the system design must consider the total I/O count and required update rates.
Q4: What software is needed to configure this scanner module?
A4: Configuration is performed using Rockwell Automation's RSLogix 500 programming software. The scanner's parameters, such as rack addressing and communication rates, are set within the controller's project file.
Q5: Does the 1747-SN module support diagnostic capabilities?
A5: Yes, the module features status indicator LEDs that provide visual feedback on communication health, scanner activity, and any fault conditions, aiding in quick system diagnostics.
Q6: Can this module be used in hazardous locations?
A6: The 1747-SN is designed for standard industrial environments. For use in hazardous locations, it must be installed within an appropriately rated enclosure that meets the local and application-specific safety standards and certifications.
Q7: What are the key benefits of using a Remote I/O system like this?
A7: The main benefits include reduced wiring costs and labor, increased system design flexibility, easier maintenance and troubleshooting, and the ability to localize control near the machine or process for improved performance.
Q8: Is the 1747-SN still manufactured, and is it considered a legacy product?
A8: The SLC 500 platform, including the 1747-SN, has been superseded by newer platforms like CompactLogix and ControlLogix. However, it remains widely used in existing installations, and modules are available through authorized distributors and specialized suppliers like Rossonix for maintenance, repair, and operations (MRO) and system upgrades.
