Series F4P Process Temperature Control
1/4 DIN, PID, Auto-Tuning, Modbus Comms
High Performance Process Controller - Offers Versatility & Ease of Use

The Watlow Series F4P 1/4 DIN temperature process controllers offer the performance and features to meet a wide range of industrial processing needs. The F4 process controllers are ideally suited for semiconductor manufacturing equipment, plastic processing and packaging equipment, and industrial process control applications.

This competitively priced controller features a four line, high definition LCD interface display along with an information key that makes set up and control operation significantly easier with less chance for error. A 16 bit microprocessor support all the accuracy and performance advantages that you have come to expect from a Watlow controller.

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

The four digital inputs can be used to remotely modify the operation of the controller or enable the display of pre-defined operator messages.

Serial communication and dual alarm relays are included in the base unit. The Series F4P 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 Series F4P controller is manufactured by ISO 9001 registered Watlow Controls and is backed with a three-year warranty. Two to four day availability on all standard models.
