These competitively priced controllers feature a four line, high definition LCD interface display that makes profile programming and controller configuration significantly faster and easier. A 16 bit microprocessor supports all the accuracy and performance advantages you have come to expect from a Watlow control.

Up to 256 steps can be programmed into as many as 40 namable profiles. Profiles can be programmed to wait for events or for up to three different process variables. A guaranteed soak feature allows you to set how closely your process needs to be controlled.

The four digital event inputs can be programmed to remotely start, pause or terminate any of your preprogrammed process recipes. The eight event outputs are segment programmable, or three of them can be assigned to programmable compressor and boost heat/boost cool control. A real time clock can be used to start a profile at any time.

Serial communication and dual alarm relays are included in the base unit. The Series F4 ramping controllers are 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 F4 controllers are manufactured by ISO 9001 registered Watlow Controls and backed by a three-year warranty.

The enhanced programming features found in the Series F4 ramping controllers are the result of listening to our customers' demand for greater capabilities with reduced programming complexity.

A profile guide leads the programmer through the programming process by offering choices for step configuration. For better operator recognition profiles and digital I/O used for events can be given names of up to 10 characters in length.

Five step types including ramp, soak, jump, auto start and end offer the programmer complete flexibility.

Ramp steps can be based on time or rate. Ramp and soak steps can be programmed to wait for up to four event inputs and three process variables. Up to eight event outputs are step selectable. Since your thermal systems characteristics may change over its operating range, up to 10 sets of PID heat/cool parameters are step selectable. The auto start step can start a profile based on a set date, a day of the week, or daily, the choice is yours. The jump step can be used to jump within a profile or to another profile. The end step terminates a program with the control outputs programmed to your process needs.

EIA-232 and EIA-485 serial communication interfaces are included in the base unit of both the Series F45 (single channel) and the Series F4D (dual channel) controllers. The baud rate is selectable as either 9600 or 19200 K baud. The protocol is Modbus™ .
