The Mitsubishi PLC Controller Module FX3SA-10MR-CM / FX3SA-10MT-CM is a compact yet powerful entry-level controller engineered for reliable, real-time control in demanding industrial environments. Its modular architecture supports up to 10 I/O points with relay or transistor output options, making it an ideal choice for small-scale automation, standalone machines, and retrofit applications. The FX3SA series delivers exceptional performance with a rich set of internal resources including high-speed counters, EEPROM-latched data storage, and flexible expansion capabilities, all while maintaining the proven reliability of Mitsubishi’s MELSEC family.
