FX3S-10MT/ESS - Mitsubishi Programmable Controllers Melsec

The Mitsubishi FX3S-10MT/ESS PLC is engineered to deliver reliable control in small-scale automation systems. Operating on a wide 100–240V AC power supply, it features a non-volatile EEPROM memory with 16K program steps, ensuring that logic sequences are preserved even in the event of power failure. With 6 digital inputs and 4 transistor outputs using source logic, this controller is ideal for basic sequencing, signal switching, and simple actuator control.

Although compact, the FX3S-10MT/ESS offers fast instruction execution with a 210 ns LD cycle time and 500 ns MOV cycle time, making it responsive enough for time-sensitive control loops. It supports a fixed 30 I/O point capacity and is not expandable, simplifying design for fixed-scope applications. The unit supports ambient operation up to 55°C, consumes only 19W of power, and includes an IP10-rated housing that suits standard control cabinet installations.

With built-in communication via RJ45 Ethernet and RS-485, it enables seamless data exchange across field devices and supervisory systems. The PLC is compliant with international certifications including CE, UL/cUL, UKCA, and multiple shipping authority approvals like ABS, BV, DNV GL, LR, and NK, making it suitable for both land-based and marine applications. Thanks to Mitsubishi’s rugged build quality, integrated EMC filtering, and dependable operation at switching frequencies up to 16 kHz, the FX3S-10MT/ESS remains a trusted controller for compact yet demanding automation needs.

The FX3S-10MT/ESS is an ideal choice for simple industrial applications such as packaging lines, panel-mounted safety logic, pump and fan control, or basic machine automation. Its fixed I/O setup and compact size make it a perfect fit for systems where additional expansion is unnecessary, yet reliability is essential.

In a real-world scenario, this Mitsubishi PLC could control a labeling machine, taking inputs from proximity sensors and triggering output relays for stepper motors. With fast response time and reliable EEPROM program storage, even entry-level automation tasks can achieve stable, uninterrupted performance. The transistor outputs allow high-speed switching without mechanical wear, while its AC input voltage range (100–240V) provides flexibility across different electrical environments.

Maintenance engineers appreciate its ease of wiring and minimal power footprint, while engineering students can use it as a platform to understand digital control fundamentals. For OEMs and machine builders, the FX3S-10MT/ESS offers a durable, cost-effective automation solution backed by Mitsubishi’s global support network and industry-proven track record.
