Allen-Bradley 1766-L32BXBA MicroLogix 1400 controller specifications. 20 embedded I/O, 32K memory, Ethernet, AC power supply, 85-264V AC input, IP20. For industrial automation and control.

Product Overview

The Allen-Bradley 1766-L32BXBA​ is a MicroLogix 1400 programmable logic controller (PLC)​ designed for industrial automation and control applications. This model features 20 embedded I/O points (12 inputs/8 outputs), 32K words of user memory, Ethernet and serial communication ports, and operates on 85-264V AC power. The "1766" designation indicates the MicroLogix 1400 series, "L32" specifies the memory size, and "BXBA" indicates the specific I/O configuration with AC power supply. This controller provides robust control capabilities for small to medium automation applications with built-in communication options and wide-range AC power input for global applications.

Technical Specifications

Note: Specifications are based on Allen-Bradley 1766 series technical documentation. The "1766-L32BXBA" model specifically indicates 32K memory with embedded analog I/O and AC power supply. Actual specifications may vary slightly depending on production batch.

Model Number Decoding (1766-L32BXBA)

• 1766:​ Series designation (MicroLogix 1400 series)

• L32:​ Memory size (32 = 32K words)

• BXB:​ I/O configuration and features (B = 12 DC inputs/8 relay outputs, X = analog I/O, B = Ethernet)

• A:​ Power supply (A = AC power, 85-264V AC)

Note:​ The "L32" indicates 32K memory capacity. The "BXB" suffix breaks down as: First B = 12 DC inputs/8 relay outputs, X = embedded analog I/O, Second B = Ethernet port. The final "A" indicates AC power supply version. This is the AC-powered version of the 1766-L32BXB controller.

Important Technical Notes

1. Power Requirements:​ Requires 85-264V AC, 47-63 Hz power supply. Ensure adequate current capacity for controller and expansion modules.

2. I/O Configuration:​ Embedded I/O cannot be changed or expanded. Additional I/O requires expansion modules.

3. Expansion Modules:​ Supports up to 7 expansion modules (1762 series). Maximum 144 I/O points including embedded I/O.

4. Memory Capacity:​ 32K memory suitable for medium complexity applications. Consider program size and data requirements.

5. Battery Maintenance:​ Replace lithium battery every 3 years or when low battery warning appears on display.

6. Programming Software:​ Requires Connected Components Workbench (CCW) or RSLogix 500 software for programming.

7. Ethernet Configuration:​ Ethernet port requires IP address configuration (static or DHCP). Supports up to 32 connections.

8. Environmental Conditions:​ Install in appropriate enclosure for protection. IP20 provides limited protection against dust and moisture.

9. High-Speed Functions:​ High-speed counters and pulse outputs have specific wiring and configuration requirements.

10. AC Power Considerations:​ This model includes built-in AC/DC conversion. No external DC power supply required for controller operation.

Note: For complete installation guidelines, wiring diagrams, programming instructions, and detailed technical data, consult the official Allen-Bradley MicroLogix 1400 User Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
