Mitsubishi FX3G-24MR-ES-A PLC CPU Base Unit for MELSEC-F FX3G Series

The Mitsubishi FX3G-24MR-ES-A (FX3G-24MR-ES-A) is a compact programmable logic controller (PLC) CPU main unit engineered for the MELSEC-F FX3G series. Serving as the primary central processing and control unit in industrial machinery, this module features 24 integrated inputs and outputs, consisting of 14 sink/source 24 V DC digital inputs and 10 normally open relay outputs. The relay outputs support up to 2 A at 240 V AC or 30 V DC with a 10 ms response time. The CPU provides a program memory capacity of 32,000 steps in internal EEPROM and can manage up to 128 total I/O points through system expansion. For connectivity and programming, the unit incorporates an integrated USB port alongside an RS-422 communication interface, while screw terminals ensure secure field wiring for inputs and outputs. Operating on a universal supply voltage of 100 to 240 V AC, the controller is housed in a compact chassis with a width of 90 mm and supports standard DIN-rail mounting. The unit is widely deployed in discrete manufacturing, packaging equipment, material handling systems, and automated processing lines.
