The Mitsubishi Electric FX3U-16MT/ESS is a compact PLC base unit in the MELSEC-F Series that combines 8 x 24 VDC digital inputs with 8 transistor outputs in source (PNP) logic. Engineered for machine builders, OEMs, and panel integrators, it delivers dependable discrete control in space-constrained cabinets for packaging, material handling, and general automation.

Powered from AC 100–240 V, the controller provides a 64K-step RAM program capacity and fast instruction execution (LD 65 ns, MOV 642 ns) to keep sequences responsive. An RS-422 port is integrated for straightforward HMI or drive connectivity, while a USB interface is available as an option for engineering and maintenance. The unit expands up to 256 local I/O (384 including extensions), supports data retention via a buffer battery, and operates from 0 to 55 °C. Its IP10 construction and broad certifications—CE, UL/cUL, UKCA, and major marine classes—support global deployment across standardized control platforms.

Whether modernizing installed FX architectures or commissioning new compact lines, the FX3U-16MT/ESS helps shorten startup and simplify spares management within the MELSEC-F ecosystem, and with a 1-year warranty included it lets you specify with confidence while protecting your total cost of ownership.
