Allen Bradley 1747-L524 CPU Processor Unit Module

Product Introduction

The Allen-Bradley 1747-L524 CPU Processor Unit Module is a high-performance SLC 500 Series controller, optimized for small to medium-scale industrial automation tasks. Designed for SLC 5/04 and SLC 500 systems, it delivers rapid processing, reliable control, and flexible I/O management in a compact form factor.

This module features 4 KB of user memory, supporting larger and more complex control programs. With a dataspeed of 4.6 ms/k, it enables fast program execution and responsive I/O handling, ensuring timely operation in discrete and analog control applications. Its low current rating and wide operating voltage range allow efficient integration into SLC 500 backplanes while minimizing power consumption.

The 1747-L524 is suitable for standalone applications or as part of a larger SLC 500 network, providing deterministic performance, easy installation, and reliable industrial operation.
