Product Overview

1747‑L552 is SLC 5/05 Ethernet‑enabled processor for SLC‑500 modular PLC system. It executes ladder‑logic control, PID, floating‑point math and data handling for discrete‑manufacturing and process auxiliary‑control equipment. Native Ethernet enables remote programming, monitoring and plant‑network communication. Obsolete legacy Rockwell CPU; surplus and refurbished tested spare for retrofitting and spare‑part stocking of existing SLC‑500 installations.

Application Notes

‑ Check lithium‑battery condition to prevent data loss during power‑off. ‑ Use RSLogix 500 software for program download and configuration. ‑ Typical deployment: SLC‑500 PLC CPU spare‑part stocking.
