The Mitsubishi FX3U-32MT is an all‑in‑one PLC base unit that integrates power supply, CPU, and 32 built‑in I/O (16 inputs, 16 transistor outputs) in a compact housing, ideal for machine tools, packaging, materials handling, and OEM equipment. The FX3U‑32MT/ES variant uses 24V DC power with 16 DC 24V sink/source inputs and 16 transistor sink outputs, while FX3U‑32MT/ESS uses 100–240V AC power with the same 16 DC inputs and 16 transistor source outputs, giving wiring flexibility for PNP or NPN field devices. All models provide 64K‑step RAM program memory, high‑speed instruction execution (LD: 65ns, MOV: 642ns), and up to 256 local / 384 total local+remote I/O points via expansion, supporting complex logic, positioning, and networking in a small footprint.
The CPU includes built‑in high‑speed counters, positioning outputs, real‑time clock, buffer battery for retentive data and RTC, and an RS‑422 port for programming or HMI connection; USB and serial option modules can be added when needed. Protection class IP10, wide ambient range 0–55°C, and shock/vibration resistance per IEC 61131‑2 make it suitable for industrial control panels, while international approvals (CE, UL/cUL, multiple marine certifications) ensure global compliance.
