Watlow F4T Profiling and Process Control



 Watlow’s F4T Combines the Flexibility of a

Modular I/O Controller with Best-in-Class Ease of Use

The F4T with INTUITION® temperature process controller from Watlow® offers a wide range of field removable I/O
modules for maximum design flexibility. Configurations can be custom tailored to meet the scaling needs of
a tremendous range of equipment and applications while providing exactly the hardware types required for
compatibility. The F4T controller also features a 4.3 inch, color, graphical touch panel. Combining power, flexibility
and functionality, this new controller offers unmatched versatility, and its best-in-class ease of use could very
well make user manuals a thing of the past.
