MITSUBISHI FX3U-48MR/ES-A PLC Product Profile (ECER Standard, English Only)
1. Product Overview
FX3U-48MR/ES-A is a standard CPU base unit of Mitsubishi MELSEC-F FX3U compact PLC series, designed for general sequential logic control of small-to-medium automated machinery. Powered by universal AC 100–240V mains supply, the controller integrates 24-point DC24V opto-isolated digital inputs and 24-point mechanical relay outputs, total 48 built-in I/O terminals. It collects on-site sensor and limit switch signals, executes preloaded control programs to drive contactors, solenoid valves, indicator lamps and low-power actuators. Via FX3U dedicated expansion bus, users can add extra digital I/O modules, analog modules, temperature modules and communication boards to expand control capacity for diversified production line requirements.
2. Core Product Advantages
Reliable Relay Output Design: Mechanical relay contacts support AC/DC mixed load drive, wide voltage compatibility for different field actuators, convenient for conventional on-off control without intermediate relays.
Excellent Processing Speed: 0.065μs per basic instruction, up to 64K step program memory with battery backup to retain program and register data after power failure.
Flexible Expandability: Max local I/O extension up to 256 points; expand to 384 total I/O via CC-Link remote bus, compatible with full range FX3U peripheral special modules.
Built-in Multifunction Configuration: Onboard high-speed counter, built-in real-time clock, standard RS422 programming port; optional RS485/RS232 expansion boards to support Modbus RTU, CC-Link and other mainstream industrial communication protocols.
Wide Input Voltage Adaptation: AC100–240V wide-range power input resists industrial grid voltage fluctuation; built-in overvoltage and short-circuit protection circuits.
Global Safety Certification: CE, UL certified, compliant with EN61131-2 & EMC EN61000 standards, fully satisfies ECER specification for EU export and machine assembly certification.
Standard DIN Rail Installation: Compact body for cabinet layout optimization, detachable screw terminals for easy field wiring and maintenance.
