Compact PLC
 


Full PLC performance in a tiny package

It is now over 25 years since Mitsubishi Electric launched the first compact PLC on the European market. Since then Mitsubishi has become the world market leader in this sector, with over 8 million of its compact controller installations to its credit.

With their compact dimensions and low cost compact controllers have opened up new perspectives in industrial automation. Many applications for which automation was once not even an option can now benefit from the many advantages of these controllers.

The FX3U series that is now being launched worldwide is the third generation Mitsubishi Electric's extremely successful family of compact PLCs. The new flagship line once again sets new standards - and not only in the compact controllers class. The FX3U takes compact controllers into another dimension, delivering performance that was formerly the exclusive domain of larger control systems in a compact package.

The FX family now includes four independent but fully mutually-compatible product lines:
