Brief Product Description

The Allen-Bradley 1785-L40L is a high-performance PLC-5/40L processor designed for sophisticated industrial control, featuring a 48K word memory capacity. It manages up to 2048 total I/O points and provides robust communication via Data Highway Plus (DH+) and Universal Remote I/O links.

Product Description

Advanced Processing and Memory Capacity

The Allen-Bradley 1785-L40L serves as the primary processing engine for the PLC-5/40L control system. By providing 48K words of user-available memory, this module allows engineers to implement complex control logic and extensive data logging across large-scale industrial platforms. The CPU efficiently manages up to 2048 I/O points, ensuring precise control over a vast array of field devices. Because the module utilizes the proven PLC-5 architecture, it delivers the high-speed execution necessary for time-critical discrete and process automation tasks.

Comprehensive Network Connectivity

Seamless integration defines the 1785-L40L, as it supports both Data Highway Plus (DH+) and Universal Remote I/O (RIO) protocols. These built-in communication ports enable the controller to broadcast data to other processors or supervise remote I/O chassis across a distributed network. Furthermore, the module facilitates an Extended Local I/O link, allowing for the direct connection of up to 16 chassis. This networking versatility ensures that plant managers can scale their automation infrastructure without sacrificing system response or data integrity.

Reliability in Demanding Environments

Rockwell Automation engineered the 1785-L40L to maintain peak performance within harsh industrial settings. The module features integrated voltage isolation to protect sensitive logic circuitry from electrical noise and field-side surges. Since the module holds certifications from UL, CE, C-TICK, and CSA, users can trust its compliance with global safety and durability standards. Its rugged construction effectively minimizes maintenance requirements and extends the operational lifecycle of the control system, making it a reliable choice for mission-critical manufacturing processes.
