Allen Bradley 1747-L532 CPU Processor Unit Module

Product Introduction

The Allen-Bradley 1747-L532 CPU Processor Unit Module is a high-capacity SLC 500 Series controller, engineered for complex industrial automation applications that require substantial memory and large-scale I/O management. Designed for SLC 5/03 and above systems, this module provides deterministic processing for both discrete and analog control operations.

The 1747-L532 features 12K Words of program memory and 16K Words of user memory, supporting large and intricate control programs. It can manage up to 4096 input points, making it suitable for medium to large-scale automation systems. Operating across a 5–24 VDC voltage range, with a backplane current of 500 mA at 5 VDC and 175 mA at 24 VDC, the module ensures reliable, low-power integration into standard SLC 500 racks. Its combination of memory capacity, I/O handling, and efficient backplane performance makes it ideal for demanding industrial environments.
