Allen Bradley 1747-L511 CPU Processor Unit Module

Product Introduction

The Allen-Bradley 1747-L511 CPU Processor Unit Module is part of the SLC 500 Series, specifically the SLC 5/01 controller, designed for small-scale industrial automation and control applications. This CPU module provides a compact, reliable processing core with integrated memory, local I/O handling, and support for analog and digital signals, making it suitable for simple sequencing, monitoring, and discrete control tasks.

The 1747-L511 offers 1 KB of user memory, supporting the storage of control programs and parameters. It provides 960 local I/O points for direct device connectivity, along with 480 analog I/O points, enabling flexible interfacing with sensors and process signals. Its low backplane current consumption of 90 mA at 5 VDC ensures minimal power draw when installed in SLC 500 racks.

This module integrates seamlessly into SLC 500 systems, allowing communication and coordination with other modules and controllers, making it an ideal choice for compact control solutions where space, reliability, and deterministic performance are essential.
