Feimu Technology, as one of the suppliers in China, offers the Allen Bradley 1766-L32AWAA PLC. This is a powerful and durable PLC module that uses AC power supply, equipped with 32 I/O points and an integrated Ethernet interface. If your equipment is still using an old controller and you wish to upgrade, or if you are undertaking a new project and need a reliable small PLC, then this product is definitely your ideal choice. It is affordable and easy to use, and we always have it in stock.

Performance Introduction

The Allen Bradley 1766-L32AWAA model has a much faster computing speed compared to the previous 1100 series, capable of efficiently handling complex logical operations. The built-in Ethernet port eliminates the need to purchase a dedicated communication module, allowing you to directly connect to the network and program or monitor through an upper computer. It supports online editing and various expansion modules. Despite its small size, it can modify the program during machine operation and handle large tasks without stopping the machine.

Certification Advantages

Alan Bradley 1766-L32AWAA is a high-performance MicroLogix 1400 PLC specifically designed for small and medium-sized control systems. It is equipped with abundant digital and analog I/O, supports EtherNet/IP and RS-232 communication interfaces, and can be flexibly applied in complex real-time control and data acquisition scenarios. It has passed international authoritative certifications such as UL, cUL, and CE, fully meeting strict safety standards and electromagnetic compatibility requirements, providing users with an automated core that is both powerful and safe and worry-free.



Built-in Ethernet – Direct Network Connection

The 1766-L32AWAA has a built-in Ethernet port. This is one of its key advantages over older MicroLogix models that require separate communication modules.

Ethernet features:

  • Speed: 10/100 Mbps auto-negotiate.
  • Protocol: EtherNet/IP and TCP/IP.
  • Programming: Direct connection to RSLogix 500 for program upload and download.
  • HMI connection: Connect to PanelView or PC-based HMIs over Ethernet.
  • Remote monitoring: Optional web server configuration for remote status viewing.

Basic setup steps:

  1. Connect the Ethernet cable to the port on the PLC.
  2. Open RSLogix 500. Go to the controller properties.
  3. Select the Channel 1 tab (Ethernet).
  4. Enter the IP address, subnet mask, and gateway address.
  5. Download the configuration to the PLC.
  6. Verify by pinging the PLC from a PC.

Network design tip: Assign a static IP address to the PLC. This ensures the address does not change after power cycles. If the network uses DHCP, reserve the IP address in the DHCP server for the PLC's MAC address.



Built-in Analog I/O – No Separate Modules Needed

The 1766-L32AWAA includes analog inputs and outputs built into the controller. This saves panel space and reduces component cost.

Feature Specification Application
Analog Inputs 4 channels, 0-10V DC Temperature, pressure, flow sensors
Analog Outputs 2 channels, 0-10V DC VFD speed control, valve position control
Resolution 10-bit Suitable for most industrial applications

Typical applications for built-in analog:

  • Temperature control: Connect a 0-10V temperature sensor to an analog input. Use the PLC to control a heater or cooling valve.
  • Pressure monitoring: Connect a 0-10V pressure transmitter to an analog input. Set alarms for high or low pressure.
  • Speed control: Connect an analog output to a VFD. Control motor speed from the PLC program.

Comparison – MicroLogix 1400 Models

The MicroLogix 1400 series has several variants. Each model has different I/O configurations and power supply options. This comparison helps you select the correct model.

Model Power Supply Digital I/O Analog I/O Communication
1766-L32AWAA 120-240V AC 18 IN / 14 OUT 4 IN / 2 OUT Ethernet, RS-232/485
1766-L32BWA 24V DC 18 IN / 14 OUT 4 IN / 2 OUT Ethernet, RS-232/485
1766-L32AWA 120-240V AC 18 IN / 14 OUT None Ethernet, RS-232/485
1766-L32BWA 24V DC 18 IN / 14 OUT None Ethernet, RS-232/485

How to choose:

  • 1766-L32AWAA: Use when AC power is available and analog I/O is required.
  • 1766-L32BWA: Use when DC power is available and analog I/O is required.
  • 1766-L32AWA: Use for digital-only applications with AC power.
  • 1766-L32BWA (no analog): Use for digital-only applications with DC power.

Status LEDs and Troubleshooting

The 1766-L32AWAA has several LEDs on the front panel. These provide immediate status information without a programming terminal.

LED Status Meaning Action
PWR Green Controller powered and operating normally. No action needed.
PWR Off No power to controller. Check AC power. Check power supply.
RUN Green Controller is in RUN mode. No action needed.
RUN Off Controller is in PROGRAM mode. Switch to RUN mode from RSLogix 500.
RUN Flashing Controller is in PROGRAM mode with forces enabled. Check forces. Enable or disable as needed.
FAULT Red Controller fault. Hardware or software error. Check fault code in RSLogix 500. Clear fault or cycle power.
FORCE Yellow I/O forces are active. Review forces. Remove or keep as needed.
BAT Red Battery voltage low. Replace battery within 1 week.
LINK Green Ethernet link active. No action needed.

Product Authenticity Verification

Allen Bradley 1766-L32AWAA controllers are commonly counterfeited. Use these checks to verify authenticity.

  • Front panel color: Genuine controllers use a specific beige-gray color consistent with the MicroLogix family. Counterfeits often have a different shade or glossy finish.
  • Label quality: Genuine labels have permanent printing with the model number 1766-L32AWAA clearly visible. Counterfeit labels often have blurry text or peel at edges.
  • Terminal block: Genuine terminal blocks have smooth screw operation. Counterfeits often use cheap plastic with screws that stick or strip.
  • Ethernet port: Genuine units have a metal-shielded RJ45 port. Counterfeits often use plastic ports.
  • Module weight: Genuine 1766-L32AWAA weighs approximately 0.6 kg. Counterfeits often feel lighter.
