Allen Bradley 1747-OS401 SLC 5/04 Firmware Upgrade Kit

Product Overview

The Allen Bradley 1747-OS401 serves as a critical Operating System (OS) upgrade component for the SLC 5/04 controller series. This kit provides the necessary firmware chips to update the processor’s instruction set, enhance communication stability, and support advanced networking features within the SLC 500 platform. We offer this kit as 100% Brand New and Factory Original, ensuring you receive unprogrammed, pristine EEPROM/Flash components required for secure system migration or legacy hardware restoration.

Technical Specifications

The 1747-OS401 kit updates the SLC 5/04 CPU to a specific OS level to resolve compatibility issues with newer hardware revisions:

Engineering Advantages

• Enhanced Instruction Processing: This firmware upgrade expands the controller's mathematical and data-handling capabilities. It allows the SLC 5/04 to execute complex algorithms and floating-point operations more efficiently, extending the lifecycle of legacy hardware.

• Communication Protocol Stability: The 1747-OS401 resolves known handshaking issues across DH+ (Data Highway Plus) and RS-232 channels. It ensures consistent data packet delivery when the controller interfaces with modern HMI/SCADA systems or bridging modules.

• Static Protection Compliance: Each kit resides in high-grade anti-static packaging. This prevents ESD (Electrostatic Discharge) damage during transit and handling, protecting the sensitive internal logic of the firmware chips before they reach your CPU.

• System Modernization without Replacement: Installing the 1747-OS401 allows existing SLC 5/04 processors to support newer I/O modules and specialty cards. This provides a cost-effective alternative to a full system "rip-and-replace," maintaining your existing PLC-5/SLC infrastructure.

FAQs

• Is this 1747-OS401 kit 100% Brand New?

  Yes. We supply only 100% Brand New upgrade kits in original factory packaging. Since firmware chips have finite write cycles and sensitive pins, we never provide "pulled" or used components.

• Will this kit work on an SLC 5/03 or 5/05?

  No. The 1747-OS401 specifically targets the SLC 5/04 architecture. SLC 5/03 and SLC 5/05 controllers require different OS kits (such as OS302 or OS501) due to differences in their memory mapping and communication hardware.

• Do I need special tools to install the firmware?

  You require a standard chip extraction tool and a grounded ESD wrist strap. Following strict anti-static protocols prevents permanent damage to both the new firmware and the controller’s motherboard.

• What happens to my current program after the upgrade?

  The firmware upgrade process typically clears the controller's memory. You must back up your RSS project file using RSLogix 500 before starting the installation, then download the program back to the controller once the new OS initializes.
