FX3G-40MT/ESS - Mitsubishi Programmable Controllers Melsec

The FX3G-40MT/ESS PLC combines powerful logic handling with modular scalability, making it a trusted solution in both small and mid-sized automation systems. Powered by a wide 100–240V AC input, it offers versatile deployment across industries. With a 32K step EEPROM program memory, this Mitsubishi controller ensures non-volatile, battery-free program retention—a crucial feature in regions prone to unstable power supply.

Equipped with 24 digital inputs and 16 transistor outputs using source logic, the FX3G-40MT/ESS provides fast switching and precise control for equipment like solenoids, relays, valves, and actuators. Its cycle time of 210 ns (LD) and 500 ns (MOV) allows for real-time processing in time-critical systems. The PLC supports 128 local I/O points and up to 256 local + remote I/O points, making it fully expandable to meet growing operational demands in Indian factories and automation lines.

Designed for tough environments, it features a durable body rated at IP10, operates at temperatures up to 55°C, and maintains compactness with dimensions of 130 mm (W) × 90 mm (H) × 86 mm (D). It weighs only 0.7 kg, making it suitable for dense control panels. The Mitsubishi FX3G-40MT/ESS is globally approved, holding CE, UL/cUL, and UKCA certifications, along with marine-grade approvals like ABS, BV, DNV GL, KR, LR, NK, and RINA. Its performance, compliance, and scalability make it a favorite for OEM projects and industrial machine builders.

The FX3G-40MT/ESS is an ideal controller for various automation tasks where precise timing, fast execution, and compact design are critical. Commonly used in automated conveyor lines, material handling systems, filling and bottling stations, and pick-and-place machines, it ensures smooth synchronization of operations without lag. Its transistor outputs make it especially suited for high-speed switching applications where relay response would fall short.

In Indian manufacturing setups, engineers deploy this PLC in textile automation panels, packaging control units, and semi-automatic assembly systems. The EEPROM-based memory is a huge benefit for plants with frequent power fluctuations, avoiding the need for manual reprogramming. With expansion capabilities, users can start small and scale gradually—making it perfect for machine builders who cater to customized client needs.

For engineering students and maintenance professionals, the FX3G series offers an intuitive learning curve. The source-type transistor outputs provide safety and circuit isolation, while the international compliance makes it acceptable in export-based machinery as well. Overall, the Mitsubishi FX3G-40MT/ESS is a future-ready investment for industries looking to enhance automation with confidence.
