Allen-Bradley 1769-L32E CompactLogix 5332E Ethernet Controller
Allen-Bradley 1769-L32E is a CompactLogix 5332E Ethernet programmable automation controller with 750 KB of user memory, one 10/100 Mbps EtherNet/IP port, one isolated RS-232 serial port, and support for up to 16 local 1769 I/O modules across 3 banks. It uses a 1784-CF128 CompactFlash card for nonvolatile storage, is backed by a 1769-BA lithium battery, and mounts on a DIN rail or panel — a proven, economical controller for machine-level control and Ethernet networking.
Overview
The 1769-L32E belongs to the Allen-Bradley CompactLogix 1769 modular controller family, built on the Logix 5332E engine. It combines the Logix control engine with built-in EtherNet/IP connectivity, allowing direct integration with PanelView HMI terminals, drives, and supervisory systems over standard Ethernet. With 750 KB of user memory and support for up to 16 local 1769 I/O modules, it covers small-to-mid-size machines that need reliable deterministic control without the cost of a larger chassis-based system.

Applications
The 1769-L32E is widely used in packaging, conveyors, pumping, and general machine control where built-in Ethernet connectivity and compact modular hardware are required. Its native EtherNet/IP port makes it a drop-in fit for networks with PanelView terminals, drives, and SCADA systems, while the isolated RS-232 port supports legacy DF1/ASCII programming and serial devices.
