Allen Bradley 1764-24BWA MicroLogix 1500 Programmable Controller Base Unit

Product Introduction

The Allen-Bradley 1764-24BWA MicroLogix 1500 Programmable Controller Base Unit is a compact and reliable programmable logic controller designed for small-to-medium industrial automation systems. Manufactured by Rockwell Automation under the Allen-Bradley label, the MicroLogix 1500 series combines processing power, flexible input/output capability, and a modular architecture in a single compact unit.

The 1764-24BWA base unit includes a 120VAC power supply, 12 digital 24VDC inputs, and 12 relay outputs, allowing it to control motors, contactors, solenoid valves, and indicator devices. Its integrated I/O reduces wiring complexity and simplifies installation, making it ideal for standalone machines or small automation systems.

Expandable architecture ensures that additional I/O modules can be added if more control channels are needed. This scalability makes the MicroLogix 1500 suitable for both standalone and integrated production environments. Its robust industrial design allows operation under harsh conditions with consistent reliability, while compatibility with industry-standard programming software enables efficient engineering, maintenance, and troubleshooting.
