Product Overview

The 1747-L543 is an Allen-Bradley SLC 5/04 processor module within the SLC 500 family. It functions as the central processing unit (CPU) in a modular PLC control system, providing logic execution, I/O scanning, and communications. Installed in a 1746-series chassis, it supports applications across manufacturing automation, material handling, machine control, and process monitoring. The 1747-L543 handles discrete and analog signals, uses embedded DH-Plus and RS-232 for networking, and provides onboard memory for user programs and data.
