The 1769-L32E is part of the Allen-Bradley 1769 CompactLogix family, providing a compact, cost-effective controller that uses RSLogix 5000 / Studio 5000 Logix Designer and shares the Logix control engine with ControlLogix. It features 750 KB of integrated user memory (expandable with optional CompactFlash 1784-CF64/128 cards) and supports up to 16 local 1769 Compact I/O modules with a maximum of 3 I/O banks using 2 expansion cables, making it suitable for distributed and modular systems.
Communication capabilities include one EtherNet/IP port for programming, HMI/SCADA, and I/O control over Ethernet, and one RS-232 serial port supporting DF1 full/half duplex, DF1 radio modem, DH-485, Modbus (via user logic), ASCII protocols. The Ethernet port ships with BOOTP/DHCP enabled, so an IP address can be assigned using the BOOTP utility or via initial download over the serial port, after which the controller can be programmed over EtherNet/IP. The controller supports up to 32 EtherNet/IP nodes depending on system configuration, suitable for drives, remote I/O, and PanelView terminals.
Power consumption is approximately 660–850 mA at 5 V DC and 90 mA at 24 V DC, with typical heat dissipation around 4.7–6.5 W, and it has a power supply distance rating of 4 modules (the controller must be at the left end of the first bank). It operates from 0–60 °C, with 5 g vibration, 30 g operating shock, and 0–95% non-condensing humidity, and uses a 1769-BA lithium battery to retain user memory; a right (1769-ECR) or left (1769-ECL) end cap is required at the end of each I/O bank.
Programming languages include Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), and Sequential Function Chart (SFC), and the controller can manage up to 6 tasks with multiple programs per task for flexible application structuring. Typical applications span general-purpose machine control, packaging, material handling, process skids, and OEM equipment requiring integrated Ethernet, compact size, and moderate I/O counts.
