Product Overview

The 1769-L24ER-QB1B is a highly integrated, all-in-one controller from the CompactLogix 5370 L2 family. Designed for small to medium machines, it combines a high-performance processor with a built-in I/O bank of 32 digital points. By integrating the CPU, power supply, and I/O into a single form factor, it reduces panel space requirements and simplifies wiring. Dual EtherNet/IP ports provide DLR support, and a maintenance-free capacitor eliminates the need for internal batteries for memory retention.

Input & Output Characteristics

Input Thresholds: On-state current 2–5 mA; Off-state max voltage 5 V DC
Output Protection: Sourcing outputs with max voltage drop 1.0 V DC at 1.0 A
Module Capacity: Total output current limited to 4 A at 60 °C
Isolation: Integrated 24 V DC supply is isolated to protect logic from field-side electrical noise

Application Performance

The 1769-L24ER-QB1B supports deterministic control and integrated motion, with up to 4 axes of Integrated Motion on EtherNet/IP (positioning only). It is ideal for small pick-and-place, packaging, or other compact machine applications. Dual-port Ethernet enables daisy-chaining, reducing the need for external Ethernet switches in simple layouts.

Common Technical Questions

How many expansion modules can be added?
Up to 4 local 1769 Compact I/O modules. For additional I/O, consider distributed I/O over EtherNet/IP or an upgrade to the L3 series.

Does this unit require a separate power supply?
No. The controller includes an integrated 24 V DC power supply, but an external clean 24 V DC source is needed to power both the internal supply and the field-side I/O.
