The Allen-Bradley 1769-L27ERM-QBFC1B is a CompactLogix 5370 L2 Ethernet processor module engineered for demanding mid-range control applications. This controller integrates a powerful dual-core processor with embedded I/O, including 16 digital inputs, 16 digital outputs, 4 analog inputs, and 2 analog outputs, enabling compact and cost-effective system designs. Its dual-port EtherNet/IP supports device-level ring (DLR) topology for high-availability networks, while the USB and serial ports simplify programming and maintenance. The module is designed for modular expansion with up to 16 local I/O modules and 8 expansion modules, providing scalability for evolving automation needs. With 2 MB of user memory and 512 KB of non-volatile memory, it handles complex logic, motion, and data logging tasks efficiently. The 1769-L27ERM-QBFC1B operates on 24V DC power and is rated for industrial environments with an operating temperature range of -20°C to 60°C. Below are the detailed technical specifications:
