The 1766-L32AWA stands as a versatile member of the MicroLogix 1400 controller family. Designed for smaller-scale applications, this controller effectively bridges the gap between basic relay logic and more complex automation tasks. Its integrated design reduces the need for numerous external components, simplifying the overall system architecture.
Furthermore, the Allen-Bradley 1766-L32AWA excels in environments requiring reliable control and flexible connectivity. It communicates seamlessly with various devices, from simple pushbuttons to sophisticated SCADA systems. Its robust construction ensures dependable operation even in typical industrial settings. Consequently, this model remains a popular choice for machine builders and system integrators alike. Additionally, its support for multiple protocols allows for easy integration into existing networks. Specifically, the unit comes ready for demanding control tasks right out of the box.
The 1766-L32AWA controller features a comprehensive set of technical capabilities. It operates on a power supply ranging from 100 to 240V AC at a frequency of 47-63 Hz, making it suitable for global use. Its internal memory provides 20 KB of storage for user programs and data, enough for many standard control applications.
The I/O configuration is extensive for its class. The unit includes twenty (20) digital 120V AC inputs and twelve (12) relay outputs. It also features two (2) analog inputs built-in. Additionally, the controller supports up to six embedded 100-kHz high-speed counters, but only on models with DC inputs (note: this model has AC inputs). Moreover, it includes a built-in real-time clock (RTC), providing accurate time-stamping for data logs and scheduled operations.
For communication, the MicroLogix 1400 1766-L32AWA excels. It provides three distinct ports: an isolated RS-232/485 combo port, a non-isolated RS-232 port, and an Ethernet port. The serial ports support protocols like DF1, ASCII, MODBUS RTU, DNP3, and DH485. Meanwhile, the Ethernet port supports Ethernet I/P, DNP3, and MODBUS TCP/IP, enabling easy connection to HMIs and higher-level systems.
This controller is built for a standard industrial environment. Its open-style enclosure is designed to be mounted inside a control cabinet. The 1766-L32AWA measures 90 x 180 x 87 mm (3.5 x 7.087 x 3.43 in), allowing it to fit into compact spaces. Its shipping weight is roughly 2 lbs (0.9 kg), indicating its lightweight design.
Furthermore, proper installation is straightforward. The Allen-Bradley 1766-L32AWA is designed for horizontal mounting only and can be secured using either a DIN rail or panel mounting. It includes a debris strip to protect its internal electronics from dust and dirt during installation. Importantly, this strip should be removed once all mounting and wiring tasks are completed to ensure proper ventilation.
Mounting the 1766-L32AWA correctly is key to its reliable operation. First, choose a clean, dry location within an enclosure that does not exceed Over Voltage Category II. The controller supports two primary mounting methods: securing it directly to a grounded mounting plate with screws, or clipping it onto a standard DIN rail.
Next, ensure that the surrounding environment is free from excessive conductive dust and moisture. During panel installation, keep the debris strip in place to shield the circuitry from any metal filings or dust. When wiring, use copper conductors rated for the appropriate temperature and voltage. Finally, connect the power supply to the designated terminals, ensuring the correct voltage is applied. Always verify that all connections are secure before powering on the unit.

What is the difference between the RS-232 and RS-485 ports on the 1766-L32AWA?
The 1766-L32AWA has one isolated combo port that can be configured as either RS-232 or RS-485, and a second non-isolated RS-232 port. The RS-485 allows for longer distance, multi-drop communication, while RS-232 is typically used for point-to-point connections.
Can I expand the I/O capabilities of this MicroLogix 1400 controller?
Yes, you absolutely can. The Allen-Bradley 1766-L32AWA supports expansion by allowing you to connect up to seven additional 1762-series expansion I/O modules to increase its total I/O point count.
Does the 1766-L32AWA support the DNP3 protocol for communication?
Yes, it does. Both the serial and Ethernet ports of the 1766-L32AWA support the DNP3 protocol, making it suitable for specific applications like water/wastewater and utility monitoring.
What is the function of the built-in Real-Time Clock (RTC)?
The RTC in the 1766-L32AWA provides a time reference for applications. This allows for scheduled control, time-stamping of alarm events, and data logging, which are critical for process tracking and diagnostics.
Is programming software included in the packaging?
No, programming software like RSLogix 500 or CCW is not included. However, software can be purchased separately from authorized distributors. The system can be programmed via the built-in serial or Ethernet ports.
