Description

Product Overview

The Allen-Bradley 1747-L543 is a high-performance SLC 5/04 modular processor designed for the Allen-Bradley SLC 500 control system family. Equipped with 64 KB of battery-backed user memory (60K words for program/data and 4K words for data only), this central processing unit supports up to 4,096 discrete inputs and 4,096 discrete outputs across multiple chassis. It features built-in communication interfaces including a 9-pin RS-232 port and a 3-wire terminal Data Highway Plus (DH+) protocol port for distributed network connectivity. Operating reliably in temperatures ranging from 0 to 60°C, the processor module has a net weight of 0.50 kg (1.10 lbs).

Key Advantages

  • High Memory Capacity: Features 64 KB (64,000 words) of battery-backed RAM designed to handle large medium-to-large scale control algorithms.
  • Integrated DH+ and RS-232 Ports: Facilitates high-speed peer-to-peer communication and programming via Data Highway Plus and serial protocols.
  • Extensive I/O Scalability: Supports up to 4,096 total input points and 4,096 output points across distributed chassis architectures.
  • Fast Execution Speed: Delivers an average program scan time of 0.9 ms/K and rapid I/O scan speeds for time-critical automation.
  • Comprehensive Diagnostic Indicators: Front-panel status LEDs provide instant visual feedback on run state, CPU faults, battery status, and communication channels.
