The 1/4 DIN, single-channel, industrial Watlow F4S ramping temperature controller is easy to set
up and operate. The Watlow F4S ramping temperature controller is the perfect solution for the most
demanding ramp and soak processing applications. The features and performance of Watlow F4D ramping
temperature controllers make them ideally suited for environmental chamber or furnace and oven applications.
Competitively priced, the Watlow F4S ramping temperature controller features a four line, high definition
LCD interface display that makes profile programming and controller configuration significantly faster and
easier. The Watlow F4S ramping temperature controller is equipped with a 16-bit microprocessor which
supports all the accuracy and performance advantages you have come to expect from a Watlow controller.
Up to 256 steps can be programmed in the Watlow F4S ramping temperature controller into as many as 40
nameable profiles. Profiles can be programmed to wait for events or for up to three different process
variables. The Watlow F4S ramping temperature controller features a guaranteed soak feature that 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 Watlow F4S ramping temperature controller's 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 Watlow F4S ramping temperature 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. Watlow F4S ramping temperature
controllers are 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.
