Allen Bradley 1769-L24ER-QBFC1B CompactLogix 5370 L2 Controller

Product Overview

The Allen Bradley 1769-L24ER-QBFC1B acts as a versatile, high-performance controller within the CompactLogix™ 5370 L2 family. This processor integrates motion control, safety, and standard drive capabilities into a single, compact platform. It provides a robust solution for small-to-medium machine applications by combining 750 KB of user memory with extensive embedded I/O. We supply this unit as 100% brand new and original, ensuring your automation system benefits from the latest hardware revision and full manufacturer integrity.

Technical Specifications

The 1769-L24ER-QBFC1B utilizes a sophisticated hardware architecture to manage complex logic and communication tasks:

Engineering Advantages

• Embedded I/O Density: This controller features high-density embedded I/O points, reducing the need for additional expansion modules. This configuration lowers the total system cost and significantly shrinks the control cabinet footprint.

• Dual-Port Ethernet Connectivity: The integrated dual Ethernet ports support Device Level Ring (DLR) topologies. This ensures network resiliency; the system maintains communication even if a single point in the network ring breaks, preventing unplanned downtime.

• Enhanced Memory Reliability: Every unit ships with a 1784-SD1 1 GB Secure Digital card. This nonvolatile storage preserves your program and data tags without requiring a battery, simplifying long-term maintenance.

• Flexible Mounting and Installation: The hardware supports both DIN rail and panel mounting. Use M4 or #8 screws with a torque of 1.1–1.8 N·m to ensure a secure installation in high-vibration environments.

• Robust Signal Integrity: The 30V continuous isolation protects the logic system from field-side noise. The module passes 500V AC testing for 60 seconds, ensuring electrical safety and reliable signal processing in harsh industrial zones.

FAQs

• What type of wiring does the 1769-L24ER-QBFC1B require for power terminals?

  Use 22–14 AWG solid copper wire rated at 75 °C (167 °F) or higher. Strip the insulation to 8 mm (0.31 in) and tighten the screws to a torque of 1.0–1.2 N·m (8.9–10.6 lb·in) to ensure a gas-tight, vibration-resistant connection.

• How many expansion modules can I add to this controller?

  The 1769-L24ER-QBFC1B supports a maximum of four (4) local 1769 Compact I/O modules within a single I/O bank. This allows for tailored expansion if the embedded I/O does not meet your specific project requirements.

• Is this product a brand new Allen Bradley original?

  Absolutely. We guarantee that every 1769-L24ER-QBFC1B unit we ship is 100% brand new in original factory-sealed packaging. We do not provide refurbished or used hardware.

• Does the controller require a separate power supply for the logic?

  The unit features an embedded 24V DC isolated power supply. You must provide a stable 24V DC input to the power terminals to energize the controller and the local I/O bank.
