    Watlow's F4S 1/4 DIN single-channel industrial ramping temperature controller is easy to set up and operate. This ramping temperature controller is the perfect solution for the most demanding ramp and soak applications. The features and performance make them ideally suited for environmental chamber or furnace and oven applications.

    Competitively priced, the F4S temperature controller features a four line, high definition LCD interface display that makes profile programming and controller configuration significantly faster and easier. The controller is equipped with a 16-bit microprocessor which provides accuracy and performance making this a very reliable ramping temperature controller.

    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 programmed 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. In addition, the controller has a real time clock which can be used to start a profile at any time.

    Serial communication and dual alarm relays are included in the base unit. The controller is packaged with a NEMA-4X front face to withstand harsh environments and a 101.6 mm (4.0 in.) deep case with removable connectors for wiring convenience.

    The Watlow F4S ramping temperature controller is backed by a three-year warranty.
