AL2-14MR-A - Mitsubishi Programmable Controllers Melsec

The AL2-14MR-A by Mitsubishi Electric combines compact form with dependable functionality, offering an input voltage range of 100–240V AC, making it compatible with most industrial power supplies. This programmable logic controller features 8 digital inputs and 6 relay outputs, making it suitable for logic-based tasks involving sensors, switches, or actuators. Its 200-block program memory is stored securely in EEPROM, ensuring program retention even without a buffer battery.

Despite its small size, the AL2-14MR-A PLC provides control for up to 14 local I/O points and offers limited expandability to meet future automation needs. It operates efficiently in environments ranging from –25°C to 55°C and is built to IP20 protection standards, making it suitable for protected control panels. The unit’s footprint—just 124.6 mm wide, 52 mm deep, and 90 mm high—saves valuable panel space, while its weight of 0.3 kg ensures easy mounting and maintenance.

With certifications including CE, UL/cUL, UKCA, and DNV marine approval, the Mitsubishi AL2-14MR-A stands as a globally trusted PLC in industries such as HVAC, lighting control, water treatment, and packaging. It delivers consistent performance and requires minimal configuration time, making it an excellent fit for both OEM applications and retrofit projects.

The Mitsubishi AL2-14MR-A PLC is best suited for controlling lighting panels, irrigation systems, basic machine operations, and building automation units. Its small footprint and relay-based output system make it a perfect choice for localized control where high-speed switching is not required but robust logic handling is critical.

For instance, in an industrial motor control setup, this PLC can receive input from push buttons, limit switches, or level sensors, and then operate relays that manage contactors or alarms. It can be programmed with basic timers, counters, and logic operations, providing just the right level of automation for simple processes. Thanks to its EEPROM-based memory, no external battery is needed, which reduces maintenance and simplifies long-term use.

Indian engineers and technicians working in sectors like agriculture, commercial infrastructure, or decentralized water pumping stations can depend on the AL2-14MR-A for quick deployment, reliable performance, and long service life. Students and automation trainees can also use it as a foundational model to understand control logic. Backed by Mitsubishi’s global reputation, this PLC delivers functionality, affordability, and ease of integration across a wide range of industries.
