Allen Bradley 1785-L40C15 PLC-5/40C Processor

Product Introduction

The Allen Bradley 1785-L40C15 PLC-5/40C Processor is a high-capacity programmable controller designed for industrial automation systems that require reliable control performance and expanded memory capability. Developed by Rockwell Automation and released under the Allen-Bradley PLC-5 product family, the processor is widely used in manufacturing plants and process control environments.

The processor is equipped with 48 Kiloword SRAM memory, enabling it to handle complex ladder logic programs and large automation tasks. Designed for installation in a PLC-5 rack system, the module communicates with I/O modules and other system components through the backplane. With a 5 VDC power requirement and 3 Amp backplane current, the 1785-L40C15 delivers stable and consistent operation for large industrial control systems.
