Allen Bradley 1747-M3 UVPROM Memory Module

Product Introduction

The Allen-Bradley 1747-M3 UVPROM Memory Module is a non-volatile program storage device developed for SLC™ 500 programmable controller systems. It is designed to store user application programs securely outside of the processor’s volatile memory, providing a dependable method for long-term program retention and controlled program distribution.

Using UV-erasable PROM (UVPROM) technology, the 1747-M3 is well suited for applications where program integrity and controlled modification are required. Once programmed, the stored logic remains unchanged until intentionally erased using ultraviolet light, making it ideal for standardized machines and validated control systems.

With an 8 KB memory capacity, the 1747-M3 supports small to medium SLC 500 control programs and is commonly applied in stable automation environments where logic updates are infrequent and program protection is a priority.

Product Specifications

Applications

• Standardized machine control systems where program changes must be tightly controlled

• Validated industrial processes requiring fixed logic and protection against accidental modification

• Production equipment replication, ensuring identical control programs across multiple machines

• Legacy SLC 500 installations with stable and infrequently changed logic

• OEM equipment delivered with pre-installed, protected control programs

• Automation systems where long-term data retention without batteries is required

Advantages

• UVPROM-based program protection, preventing unauthorized or accidental logic changes

• Non-volatile, battery-free design, ensuring reliable long-term data retention

• Stable program storage, ideal for applications with fixed control requirements

• Simple integration with SLC 500 CPUs, no changes to system architecture

• Reliable industrial construction, suitable for continuous operation

• Supports disciplined change management, making program revisions intentional and traceable
