Information About 1769-L27ERM-QBFC1B
The 1769-L27ERM-QBFC1B belongs to the 5370 CompactLogix L2 family from Allen-Bradley, designed for scalable control solutions in compact form factors. It includes 16 embedded 24 VDC digital inputs, 16 embedded 24 VDC digital outputs, 4 analog inputs, 2 analog outputs, and 4 high-speed counter (HSC) outputs. With 1 MB user memory and support for up to 32 tasks and 100 programs per task, it can manage complex automation routines. The controller features two EtherNet/IP ports that allow for linear and ring topologies, supporting up to 16 motion axes over Ethernet. It also comes with a USB port for programming and data exchange, and supports one local expansion bank with up to four 1769 Compact I/O modules.
Key Features:
- Memory & Processing: 1 MB user memory with support for up to 32 tasks and 100 programs per task for advanced control.
- Embedded I/O: Includes 16 digital inputs (24 VDC sinking/sourcing), 16 digital outputs (24 VDC sourcing), 4 analog inputs, 2 analog outputs, and 4 HSC outputs.
- EtherNet/IP Communication: Dual ports supporting linear and ring topologies, with integrated motion control for up to 16 axes.
- Additional Interfaces: One USB port for programming and configuration, plus removable 1 GB SD card for data integrity and storage.
- Expansion Capability: Supports up to four 1769 Compact I/O modules and one local expansion bank for scalable system design.
- Energy Storage: Built-in capacitor-based storage eliminates the need for lithium batteries, reducing maintenance.
- Motion Support: Provides integrated motion on EtherNet/IP, enabling advanced drive and servo integration.
- Design Efficiency: Compact chassis footprint saves up to 40% panel space while delivering high performance.
The 1769-L27ERM-QBFC1B delivers the reliability and precision required for compact automation systems, integrating control, communication, and motion in one module.
