The Mitsubishi Electric FX3U-48MT/ESS is a compact 48-point PLC base unit from the MELSEC-F FX3U series, engineered for reliable machine and line control in OEM and panel-building applications. With an AC 100–240 V power supply and fast transistor outputs, it delivers dependable performance for discrete automation, motion interlocks, and high-speed sequencing.

Equipped with 24 x 24 V DC inputs and 24 sourcing transistor outputs, the controller supports rapid cycle execution and precise signal handling. A generous 64K-step RAM program memory with battery backup supports complex logic, while instruction speeds down to 65 ns (LD) and 642 ns (MOV) enable responsive control. Connectivity includes an onboard RS-422 port and optional USB, and the unit integrates seamlessly with FX3U expansion options to scale local I/O up to 256 and total points up to 384. Certified to CE, UL/cUL, and UKCA and accepted by major marine societies, it operates reliably from 0 to 55 °C on the plant floor.

Designed to reduce commissioning time and lifecycle cost, the FX3U-48MT/ESS combines robust diagnostics with flexible expansion, making it a solid choice for standard machines and retrofit projects alike, and it comes with a 1-year warranty to support confident procurement.
