The Allen-Bradley 1747-L552 is an elite SLC 5/05 Modular PLC Processor CPU Module engineered by Rockwell Automation. Designed specifically for medium-sized control architectures, it bridges legacy hardware reliability with fast, web-enabled connectivity. The standby feature of this unit is its internal EtherNet/IP port, providing high-performance peer-to-peer messaging, remote programming capabilities, and data exchanges without needing external communication adapters.
Equipped with a lightning-fast typical execution scan time of 0.9 milliseconds per K words, the 1747-L552 processes sophisticated ladder logic arrays effortlessly. A reliable battery-backed RAM structure coupled with an option for 1747-M13 Flash backup ensures your automation processes remain safe from unexpected power loss. Its robust front panel features key switches for runtime protection and active LED indicators for quick diagnostics of system errors, battery health, and network connectivity.
