Watlow F4 1/4 DIN Temperature Process Controllers

Watlow F4 1/4 DIN Temperature Process Controllers
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, plastic processing and packaging equipment and industrial process control applications.
This controller features a four line, high definition LCD interface display, in addition to an information key that enables easy setup 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 features include cascade, ratio, differential, duplex slide wire and retransmit options. Serial communication and dual alarm relays are included in the base unit. The SERIES F4 is packaged with a NEMA 4X front face to withstand harsh environments and a four-inch (101.6 mm) deep case with removable connectors for wiring convenience. It is manufactured by Watlow, ISO 9001 registered and protected by a three-year warranty.
