Allen Bradley 1766-L32BWAA MicroLogix 1400 Programmable Controller

Product Introduction

The Allen-Bradley 1766-L32BWAA MicroLogix 1400 Programmable Controller is a versatile PLC designed for small to medium industrial control applications. Manufactured by Rockwell Automation under the Allen-Bradley label, this controller provides discrete relay outputs and analog I/O capabilities, allowing precise control of machinery and process automation systems.

With 12 discrete relay outputs, 4 analog inputs (12-bit, 0–10 VDC), and 2 analog outputs (12-bit, 0–10 VDC), the 1766-L32BWAA can manage a variety of input/output devices and execute complex control logic. The controller features 20 KB of user memory for storing ladder logic programs and process data, supporting moderately sophisticated automation tasks.

This controller operates on 120/240 VAC power supply, with an operating frequency of 47–63 Hz and a power consumption of 120 VA. It is engineered to provide stable and reliable performance across standard industrial conditions and integrates seamlessly with MicroLogix 1400 expansion modules for scalable system configurations.

The 1766-L32BWAA is widely used in manufacturing machines, material handling systems, process control lines, and building automation. Its combination of relay outputs, analog I/O, and expandable memory makes it a flexible solution for engineers seeking reliable PLC control for both discrete and analog processes.
