Mitsubishi Electric MELSEC-F FX1S‑14MR‑ES/UL is a compact programmable logic controller (PLC) basic unit with integrated power supply, CPU and I/O. Provides 8 digital inputs (24 V DC, sink/source configurable) and 6 relay outputs (2 A per point, 250 V AC / 30 V DC). Program memory 2,000 steps (EEPROM) with 0.55‑0.7 μs LD instruction execution time. Built‑in high‑speed counter function, real‑time clock, hour‑meter function, and 24 V DC/400 mA sensor power supply. 100‑240 V AC power supply, screw terminal block, DIN rail mounting. This product has been discontinued by the manufacturer and is available as a spare part for maintaining existing FX1S‑based automation systems.

Applications:

  • Small machine automation and control panels

  • Conveyor systems and material handling equipment

  • Packaging machinery and assembly line control

  • OEM equipment requiring small‑footprint PLC with relay outputs

  • Legacy system replacement and spare part stocking for FX1S configurations

System Integration:

  • This CPU unit belongs to the Mitsubishi Electric MELSEC‑F FX1S series.

  • Mounts on 35 mm DIN rail or panel mount.

  • FX1S series cannot be expanded with extension modules, but a BD board can be installed to extend a small number of I/O points and achieve RS‑232C, RS‑485, or RS‑422 communication.

  • Built‑in RS‑422 programming port supports connection to GX Works2 or GX Developer software (version 8.72A or higher).

  • Transistor output (MT) models provide 2‑axis independent 100 kHz pulse output for servo/stepper motor positioning.

  • For detailed installation, wiring and programming, refer to the MELSEC‑FX1S Hardware Manual.

Product Status:
Discontinued as of December 1, 2015. Available as a spare part for maintaining existing FX1S‑based systems while stocks permit. Recommended replacement: FX3S‑14MR/ES (MELSEC‑F FX3S series). Mitsubishi Electric accepts product repairs for seven years after production discontinuation.
For new installations, use the recommended successor.
