FX3S-30MT/ESS-2AD - Mitsubishi Programmable Controllers Melsec

The Mitsubishi FX3S-30MT/ESS-2AD PLC is purpose-built for compact control systems that demand stable performance, simple wiring, and dependable signal handling. Operating on a broad 100–240V AC power supply, it comes equipped with a 16K step EEPROM memory to retain program logic even during power outages—perfect for scenarios where battery backup is not feasible. With 16 digital inputs, 14 transistor outputs using source logic, and 2 integrated analog inputs, this unit allows hybrid digital-analog control for small machines or standalone processes.

The FX3S-30MT/ESS-2AD delivers a fast instruction cycle time of 210 ns (LD) and 500 ns (MOV), offering the precision needed for high-speed automation tasks. While its I/O is fixed at 30 points (non-expandable), it meets the needs of many space-constrained applications with minimal overhead. The compact form factor—100 mm width × 90 mm height × 75 mm depth—fits easily in small enclosures, while the IP10-rated housing ensures safety in controlled environments. Weighing just 392 grams, it’s optimized for ease of mounting and minimal power consumption at only 21W.

Communication capabilities are built-in, featuring a RJ45 Ethernet port and RS-485 interface for smooth connectivity to SCADA systems, HMIs, or external devices. Certified under CE, UL/cUL, UKCA, and marine-grade standards like ABS, BV, DNV GL, LR, NK, this MELSEC-F Series PLC is trusted in both industrial automation and maritime control systems. Its performance remains reliable up to 55°C and supports adjustable switching frequencies between 2–16 kHz, enabling precise motor and process control.

The FX3S-30MT/ESS-2AD is ideal for applications that require reliable logic control in a small footprint, such as packaging machines, labeling units, pump controls, or small conveyor systems. With its built-in analog inputs, it can handle basic process parameters like temperature, pressure, or flow — making it useful in industries like food & beverage, textile, or chemical batching where both digital and analog signals are present.

In real-world scenarios, this Mitsubishi PLC can read analog signals from level sensors and use digital outputs to control solenoid valves, all while monitoring the system status over Ethernet. Its compact size helps in space-limited panels, especially in OEM machines where simplicity and reliability matter more than modular expansion. The transistor outputs allow fast, wear-free switching, extending component life and enabling smooth motor or relay operations.

Maintenance engineers appreciate the fast startup, minimal configuration, and built-in communication ports, while students and trainees find it approachable for learning ladder logic programming and control design. With no need for expansion modules or buffer batteries, it becomes a low-maintenance solution for durable, long-term deployment. Whether you're automating a small process or standardizing simple machines, the FX3S-30MT/ESS-2AD offers solid performance, Mitsubishi reliability, and true plug-and-play simplicity.
