Allen-Bradley 1769-L35CR Compact IO Controller

Allen-Bradley 1769-L35CR CompactLogix ControlNet CPU is a compact industrial controller designed for centralized processing and distributed I/O over ControlNet networks. It includes 1 x RS-232 serial port (DF1/ASCII), 1 x ControlNet Port (Channel A), 1 x Redundant ControlNet Port (Channel B), and 1 x NAP Port, and it ships with 1.5 MB of memory for the user program and data. The L35CR supports up to 30 local Compact I/O modules, enabling scalable I/O configurations for small- to mid-sized automation tasks. As a member of the CompactLogix line, it provides built-in communications capabilities for EtherNet/IP and ControlNet networks, allowing programming, monitoring, and data exchange across plant networks. This controller is typically deployed to coordinate logic and data flow across distributed ControlNet I/O racks, making it well-suited for manufacturing lines, packaging equipment, conveyors, and other discrete automation applications where centralized control and reliable remote I/O connectivity are required. With integrated ControlNet connectivity and support for a broad range of 1769 Compact I/O modules, the 1769-L35CR offers a streamlined, single-box solution for ControlNet-centric architectures without the need for additional network modules.
