Watlow’s Series F4 1/4 DIN industrial controllers offer an easy to setup and operate solution for the most demanding ramp and soak processing applications. The features and performance of these units make them ideally suited for environmental chamber or furnace and oven applications. Single and dual channel versions are available.

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 nameable 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. Two to four day availability on all standard models.
