The FX3U-80MR/ES-A is a high-capacity compact main base unit from Mitsubishi MELSEC-FX3U 3rd generation micro PLC series, serving as the core logic controller for medium-sized small automation systems. It integrates built-in CPU, power supply, memory and complete digital I/O terminals in one compact body. Powered by universal AC 100–240V mains, it carries 40 DC 24V sink/source compatible digital inputs and 40 mechanical relay outputs. The unit executes ladder logic, arithmetic, high-speed counting, pulse positioning and serial communication tasks, supporting flexible I/O expansion, analog modules and fieldbus adapters. With reliable relay contact switching for mixed AC/DC field loads, it delivers cost-effective all-in-one control for packaging, conveyor, textile and general machinery without separate power and CPU modules.

⚡ Universal Wide-Voltage AC Power Supply 100–240 VAC single-phase input adapts to global factory power grids, eliminates transformer conversion for cross-border equipment. 📊 Abundant Built-in I/O Resource 40 DC24V digital inputs + 40 relay outputs (total 80 I/O points) meets medium-scale machine logic demands, reduces extra expansion module investment. 🔘 Versatile Relay Output Interface Mechanical relay contacts support both AC and DC loads (max 2A per point, 8A common per 4-point group), suitable for solenoid valves, contactors, indicator lamps. 🚀 Ultra-Fast Basic Instruction Execution 0.065 μs per basic LD instruction; supports high-speed counter, pulse output positioning and floating-point arithmetic for precision motion control. 🧩 Powerful Expandable Architecture Max total 256 local I/O after adding extension modules; supports analog, temperature, positioning and communication special function blocks. 💾 Large Program & Data Storage 64K steps built-in program memory; backup lithium battery retains registers, timers and counter data during power outage. 📡 Multi-Channel Built-in Communication Standard RS-422 programming port; expandable RS-485, RS-232, Ethernet and CC-Link for HMI, inverter and upper computer networking. 🛡️ Complete Industrial Self-Diagnosis Integrated power detection, battery low alarm, program error, I/O short-circuit diagnosis LED indicators for fast on-site troubleshooting. 🌡️ Rugged Compact Cabinet Design IP10 protection class, 0°C ~ 55°C stable operating temperature; lightweight compact structure saves control cabinet installation space. 🏅 Global Authorized Certifications CE, UL, cUL, RoHS, KC certified for worldwide machinery export and industrial application compliance.
