The 1769-L27ERM-QBFC1B is a high-performance CompactLogix 5370 L2 Packaged Controller. It is an “all-in-one” solution that integrates logic, motion, and extensive onboard I/O into a single compact module, making it ideal for distributed automation systems.
Core Specifications
- Memory: 1 MB user memory.
- Onboard I/O: Features 16 DC inputs, 16 DC outputs, 4 universal analog inputs, and 2 analog outputs (supporting voltage/current).
- High-Speed Features: Includes 4 high-speed counters and support for up to 4 axes of CIP Motion.
- Communication: Dual EtherNet/IP ports with Device Level Ring (DLR) support and a USB port for programming.
Key Technical Features
- Integrated Control: Combines discrete, analog, and motion control in one device, reducing the need for multiple separate modules.
- Scalability: While it has significant onboard I/O, it also supports expansion for up to four 1769 Compact I/O modules.
- Network Resiliency: The dual EtherNet/IP ports allow for linear or ring (DLR) topologies, ensuring the system stays online even if a cable is disconnected.
- Industrial Readiness: Operates on 24 VDC, functions between 0–60 °C, and carries multiple certifications (including Marine, UL, and CE) for use in diverse environments.
