- Combines a 512 KB CompactLogix controller with embedded digital, analog, and high-speed I/O
- Provides EtherNet/IP and an isolated RS-232 serial channel for machine connectivity
- Supports up to two Compact I/O expansion modules within the documented current budget
1769-L23E-QBFC1B is an Allen-Bradley compactlogix packaged controller used in CompactLogix control systems.
The controller provides a compact machine-control platform where processing, networking, local I/O, and limited Compact I/O expansion must fit a small panel footprint.
Before installation or replacement, verify Series A or B, firmware and Studio 5000 compatibility, user program and tags, Ethernet addressing, serial protocol, embedded I/O wiring and scaling, high-speed counter setup, battery, 24 V DC power, expansion-current budget, and replacement strategy.
Availability, condition, price, and shipping time for 1769-L23E-QBFC1B are confirmed during quotation.
