Product Overview
The 1769-L23-QBFC1B is an Allen-Bradley CompactLogix packaged dual-serial controller module featuring embedded digital, analog, and high-speed counter I/O. It includes 512 KB of memory and supports 16 discrete inputs, 16 discrete outputs, 4 analog inputs, 2 analog outputs, and 4 high-speed counters. As a CompactLogix platform controller, it typically serves as the core CPU for small-machine and modular control systems where integrated serial communication and mixed I/O types are required.
Best Suited For
- Small-machine control with mixed I/O
- Applications requiring serial DF1 or DH-485 communication
- Scenarios needing embedded analog signals plus discrete I/O
- Systems with limited module expansion (up to two CompactLogix I/O modules)
