Mitsubishi Electric FX3U-64MR/ES-A Programmable Logic Controller

The Mitsubishi Electric FX3U-64MR/ES-A is a 64-point DIN-rail mounted programmable logic controller (PLC) designed for compact, high-speed control in small to mid-sized automation systems. It provides 32 DC digital inputs and 32 DC digital outputs with both relay and transistor output options, powered from 24 VDC, and supports up to 64K program steps. Its CPU executes at 0.08 µs per instruction and it offers communications via RS-232C and RS-485, with expansion up to 8 additional modules to scale I/O as needed. The unit operates from 0°C to 55°C and stores from -25°C to 75°C, carrying CE, UL, and cUL certifications for industrial environments. Typical applications include conveyor systems, assembly lines, robotics, packaging equipment, and material handling where a compact yet capable PLC is essential for reliable logic processing. Common replacements include Mitsubishi FX3U-48MR/ES-A, Siemens 6ES7212-1BB23-0XB0, and Allen-Bradley 1769-L24ER-QB1B.
