Allen Bradley 1769-L24ER-QBFC1B CompactLogix Controller

The AB 1769-L24ER-QBFC1B is a powerful CompactLogix controller that combines digital, analog, and communication capabilities into a single integrated unit. With 750KB of memory, 16 digital inputs, 16 digital outputs, 4 analog inputs, and 2 analog outputs, it delivers flexible control in compact applications.

Designed for mid-range machine control, this controller supports up to four additional 1769 expansion modules and includes dual EtherNet/IP ports with Device Level Ring (DLR) support, plus a USB programming port. Its integrated I/O and compact footprint make it ideal for space-constrained panels without sacrificing performance.
