The Mitsubishi FX3U-32MTESS is a MELSEC‑F series FX3U PLC main unit that integrates the power supply, CPU and I/O in one compact housing, making it ideal for OEM machines and panel builders who need a powerful yet space-saving controller. It operates from a 100–240 VAC power supply and provides 16 integrated digital inputs and 16 integrated transistor source (PNP) Ausgänge, supporting fast, reliable control of sensors, solenoids and other 24 VDC devices.
With 64K steps of RAM program memory and a basic instruction execution time of 65 ns, the FX3U-32MTESS can handle complex logic, data processing and motion sequences with short scan times. The high-speed performance is reinforced by built-in high-speed counters and pulse outputs for positioning, enabling control of multiple low-axis motion tasks such as indexing, labeling, packaging and small material handling systems. Local I/O can be expanded up to 256 Punkte, or up to 384 points when using CC-Link remote I/O, allowing the controller to grow with the machine.
The FX3U platform supports a wide range of expansion modules for digital I/O, analog I/O, Kommunikation (RS-232/RS-485, Ethernet, CC-Link, Profibus), temperature control and high‑speed pulse outputs, many of which are compatible with existing FX2N and FX3U modules. An integrated RS‑422 port is provided for programming and connection to operator panels, while additional interfaces such as USB or Ethernet can be added via option modules. The PLC is designed for cabinet mounting and rated to operate from 0 Zu 55 °C with IP10 protection class, and carries CE, UL/cUL, UKCA and major shipping approvals for global use.
Gesamt, the FX3U-32MTESS offers a strong combination of processing power, flexible expansion and reliable PNP transistor outputs in a compact AC-powered main unit, making it well suited for packaging machines, assembly cells, textile machinery, small conveyors and other discrete automation tasks.
