Series F4 Process Controller

The SERIES F4 1⁄4 DIN temperature process controller offers performance features to meet a wide range of industrial processing needs.

The F4 process controller is ideal for semiconductor manufacturing equipment, plastics processing and packaging equipment and industrial process control applications.

This process controller features a four line, high definition LCD interface display, in addition to an information key that enables easy set up and control operation, minimizing the chance for error.

Its 16-bit microprocessor ensures accuracy and delivers performance advantages you can count on from a Watlow controller.

Four digital inputs remotely modify controller operation or enable display of pre-defined operator messages. Advanced process controller features include cascade, ratio, differential, duplex slide wire and retransmit options.
