Rossonix Co., Limited – your reliable partner in industrial automation – is proud to offer the Allen-Bradley 1747-L552 SLC500 System CPU Module. As a trusted supplier with over a decade of experience (established 2011) and annual export value exceeding US$5 million, we ensure that every module we deliver meets rigorous quality standards. The 1747-L552 is the heart of the SLC500 programmable logic controller family, providing powerful processing capability, flexible memory configuration, and seamless integration into existing control systems. Whether upgrading legacy equipment or building new automation lines, this CPU module delivers consistent performance and reliability.

The 1747-L552 (also known as 1747L552) features an enhanced 16-bit microprocessor that can handle up to 8K words of combined user program and data memory. It supports the full instruction set of the SLC500 series, including advanced math, PID loops, and high-speed counting. With an integrated DH-485 communication port, it allows easy connection to operator interfaces, programming terminals, and other SLC processors. The module is designed for use in standard 1746 backplanes, making upgrades straightforward.

Key Product Features & Technical Specifications

High-Performance Processor: Enhanced 16-bit CPU ensures fast scan times (typically 0.9 ms per 1K of logic) suitable for demanding applications.
Flexible Memory: 8K words total memory – user program and data are dynamically allocated, providing efficient use of resources.
Built-in Communication: DH-485 port supports multi-drop networking up to 32 nodes; additional serial port available for programming or ASCII devices.
Comprehensive Instruction Set: Includes over 200 instructions – timers, counters, math, comparison, data move, PID, and more.
Real-Time Clock (RTC): On-board battery-backed RTC for time-stamping events and scheduling tasks (battery included).
Diagnostic LEDs: Visual indicators for run, fault, battery, and force status simplify troubleshooting.
Easy Firmware Upgrade: Flash memory allows field upgrades via DF1 protocol without hardware changes.
Wide Temperature Range: Rated for 0°C to 60°C operation, suitable for industrial environments.

Customer Benefits

Cost-Effective Upgrade: When replacing older SLC500 processors (like 1747-L524 or 1747-L532), the 1747-L552 offers a significant performance boost without rewiring or redesigning the cabinet.
Enhanced Reliability: Allen-Bradley’s robust design ensures long service life even in harsh environments. Backed by Rockwell Automation’s global support.
Easy Integration: The DH-485 network allows seamless connection to HMI panels, drives, and other PLCs – reducing installation time.
Scalable Memory: At 8K words, this CPU can handle mid-size applications; for larger systems, consider the 1747-L553 (16K) – ask us for options.
Fast Diagnostic Feedback: Built-in error detection and LED indicators minimize downtime and simplify maintenance.

Frequently Asked Questions (FAQ)

Q: Is this 1747-L552 a new or refurbished product?
A: We stock both new original (factory sealed) and fully tested used/refurbished units. Please specify your preference when ordering. Each unit is inspected and tested for functionality.
Q: Can I use the 1747-L552 to replace a 1747-L524 or 1747-L532?
A: Yes, the 1747-L552 is a direct drop-in replacement for most SLC500 CPU modules in the same form factor. However, please check your program memory usage – the L552 has 8K words, which is larger than L524 (4K) and same as L532. Your existing program must fit within 8K. No hardware changes are needed.
Q: What kind of battery does this CPU use, and how long does it last?
A: The module uses a standard 3V lithium battery (e.g., 1747-BA). Battery life is typically 2-4 years depending on usage. The CPU has a low-battery LED indicator.
Q: Do you provide programming software or cables?
A: We do not include software licenses, but we can supply appropriate DH-485 or DF1 programming cables (e.g., 1747-CP3 or 1747-UIC). Programming software (RSLogix 500) is available from Rockwell Automation.
Q: What is the warranty period for this CPU module?
A: We offer a standard 12-month warranty against manufacturing defects. Extended warranty options are available upon request. Please contact our sales team for details.
Q: How can I verify that the module is genuine Allen-Bradley?
A: All our modules come with original labels and part numbers. We also provide a certificate of authenticity upon request. You can cross-check the serial number with Rockwell’s database.
Q: What is the typical shipping time to the USA?
A: For in-stock items, we ship within 1-2 business days. Express shipping (DHL/FedEx) takes 3-5 working days to most US destinations. Air freight or sea freight is also available for bulk orders.
Q: Do you offer quantity discounts for this CPU?
A: Yes, we offer tiered pricing for bulk orders. Please contact us with your desired quantity for a customized quote. We also source larger quantities quickly.
