Description
Product Overview
The Allen‑Bradley 1747‑L553 is the high‑end SLC 5/05 processor for SLC 500 modular PLC platform. It features 64K combined program and data memory, built‑in 10Base‑T Ethernet TCP/IP for programming, peer‑to‑peer messaging and remote monitoring, plus an RS‑232 serial channel supporting DH485, DF1 and ASCII protocolsRockwell A…. Installed in slot 0 of 1746‑series chassis, it executes ladder‑logic applications, scans local chassis I/O and communicates with remote‑I/O adapters such as 1747‑ASB. Lithium battery preserves RAM memory during power loss. Status LED indicators and key‑operated mode switch support RUN / PROG / REM modes. Widely used for legacy Rockwell SLC 500 system maintenance and spare‑part replacementRockwell A….
