CompactLogix 2MB controller

Description: The Allen-Bradley 1769-L33ERK is a ruggedized programmable automation controller (PAC) from the CompactLogix 5370 L3 family, designed for applications requiring high performance, modular scalability, and environmental resistance. The "K" suffix denotes conformal coating, which protects internal circuitry from moisture, dust, and corrosive substances, making it suitable for use in food processing, chemical plants, water treatment facilities, and other demanding industrial environments. This controller has these features: 2MB of user memory is required to handle complicated algorithms and big data volumes. Dual EtherNet/IP ports with Device Level Ring (DLR) capability ensure network redundancy. USB 2.0 port for programming and diagnostics. Support for up to 16 local 1769 I/O modules allows for flexible system expansion. A 1GB SD card is supplied (expandable to 2GB) for data logging and backup. DIN rail installation and a 24-volt DC power supply. The operating temperature range is 0°C to 60°C (32°F to 140°F). The 1769-L33ERK is suited for mid- to large-scale control systems that require strong communication, dependable performance, and environmental stress resistance.
