The Mitsubishi AL2-4EX PLC is designed as an extension unit that seamlessly integrates into the ALPHA2 Series ecosystem, providing 4 additional digital inputs for expanding control capabilities. Powered by a stable 24V DC supply, this unit ensures accurate signal acquisition for sensors, switches, and contact inputs in light-duty industrial environments.
Its ultra-compact form—just 24.5 mm deep, 53.1 mm wide, and 90 mm tall—allows easy installation in tight control panels. Despite its minimal size, the module delivers excellent build quality and vibration-resistant performance. Weighing only 0.05 kg, the AL2-4EX is easy to handle during assembly and servicing. The unit supports DC current with secure wiring terminals for stable operation even under fluctuating plant conditions.
As part of Mitsubishi’s trusted PLC product family, the AL2-4EX stands out for its reliability in cost-sensitive control projects like HVAC control, packaging machines, pump automation, or small conveyor systems. It’s a go-to module when you're dealing with limited I/O on the main unit and need fast plug-and-play expansion without reengineering the whole system. Backed by Mitsubishi’s proven control technology, this unit meets industry standards for durability, signal integrity, and ease of integration.
The Mitsubishi AL2-4EX PLC is the perfect choice when a control system needs just a few extra input points without the cost and complexity of a full controller upgrade. It’s widely used in projects where compactness and simplicity matter—such as lighting automation, water tank level sensing, and small machine control. For example, in a packaging line, this module can capture extra limit switch signals or safety interlocks not supported by the base controller.
Plant maintenance teams and junior engineers often choose the AL2-4EX due to its easy wiring, quick setup, and predictable performance. Its DC-powered operation is ideal for low-voltage installations that prioritize safety and noise immunity. With just four I/O points, it keeps wiring neat and logic programming minimal—reducing setup time and the chance of errors.
For students and entry-level automation professionals, the AL2-4EX is an excellent hands-on learning tool to understand how PLC systems scale in real-world applications. Whether you’re retrofitting an old panel or adding a new device to an existing Mitsubishi control system, the AL2-4EX PLC delivers precision, simplicity, and long-term value.
