Single channel and 1/4 DIN, the high performance Watlow F4P temperature controller supports either closed or open loop operation. The design of Watlow F4P controller utilizes the latest technology to meet very complex processing needs while maintaining an easily understood operator interface. The Watlow F4P temperature controller is ideally suited for semiconductor manufacturing equipment, plastic processing, packaging equipment, and industrial process control applications.

The competitively priced Watlow F4P temperature controller features a four line, high definition LCD interface display along with an information key. These features make set up and control operation significantly easier with less chance for error. In addition, the Watlow F4P temperature controller's 16-bit microprocessor supports all the accuracy and performance advantages you have come to expect from a Watlow controller.

The enhanced software option enables the Watlow F4P temperature controller to support complex control applications such as cascade, ratio, and differential control.

The Watlow F4P temperature controller accepts four digital inputs which can be used to remotely modify the operation of the controller or enable the display of pre-defined operator messages. Advanced features of the Watlow F4P temperature controller include cascade, ratio, differential, slidewire, and retransmit options.

Serial communication and dual alarm relays are included in the base model of the high performance Watlow F4P temperature controller. The SERIES F4 is packaged with a NEMA 4X front face to withstand harsh environments and a four-inch deep case with removable connectors for wiring convenience. The Watlow F4P temperature controller is manufactured by ISO 9001 registered Watlow Controls and is backed with a three-year warranty.
