Description

Brief Product Description

The Allen-Bradley 1761-L32AWA is a self-contained MicroLogix 1000 controller equipped with 32 integrated I/O points and an AC power supply.² This compact PLC provides a reliable and cost-effective solution for discrete control in small-scale industrial automation and machinery.³

Product Description

Integrated Control for Small-Scale Automation

The Allen-Bradley 1761-L32AWA functions as a highly efficient, all-in-one programmable logic controller designed to streamline small automation tasks. By integrating the power supply, CPU, and I/O into a single housing, this unit minimizes the hardware footprint while delivering robust logic execution. The controller features 20 discrete 120V AC inputs and 12 versatile relay outputs, which support load voltages ranging from 24V to 240V AC/DC.⁴ This configuration makes the unit particularly effective for controlling packaging equipment, material handling conveyors, and simple process loops where space and budget are primary considerations.

Advanced Logic and High-Speed Processing

Despite its small size, the 1761-L32AWA utilizes a powerful instruction set inherited from the SLC 500 family. The internal 1KB EEPROM memory stores up to 737 instruction words, protecting user programs against power loss without the need for a battery.⁵ The processor executes logic at a fast rate of approximately 1.56ms per 1K words, allowing it to handle high-speed counter functions and complex shift registers with ease. Consequently, machine builders can implement precise timing and counting operations that are essential for high-performance discrete manufacturing.

Flexible Connectivity and Industrial Durability

This MicroLogix 1000 model prioritizes ease of integration through its built-in RS-232 communication port.⁶ The port supports DF1 and DH-485 protocols, enabling direct connection to HMI panels, SCADA systems, or programming laptops via standard 1761-CBL cables. To ensure longevity in harsh environments, the hardware withstands significant shock and vibration, with ratings up to 9g depending on the mounting method. Furthermore, the unit accommodates both DIN-rail and panel mounting, providing engineers with multiple installation options in non-hazardous or Class 1 Division 2 industrial settings.
