PXR4 Details

Thermal Corporation carries a broad selection of Fuji PX series temperature controllers for an accurate and cost effective way to control the temperatures of your process. The new PXR series controllers are the newest additions to Fuji Electric’s trusted line of temperature and process controllers. They are now packed with more features and options than before, and the new low price is unbeatable!
The PXR4 temperature controller is kept in stock and starts at $204.


The Fuji PXR Series temperature controllers come in several sizes, including 1/32 DIN, 1/16 DIN, 1/8 DIN and 1/4 DIN. Every controller has the standard features from Fuji Electric’s superior controllers, as well as some addition features. In addition to auto-tuning and fuzzy control, the Fuji PXR Series comes with self-tuning— an innovation in the control field. Self-tuning automatically retunes the controller under certain conditions, without the need to revert to auto-tuning. The standard 8-segment ramp/soak feature is now expanded to include two patterns that can be linked to create a 16-step profile.

The PXR accepts temperature and process inputs. There is a choice of three different kinds of outputs to meet a wide variety of needs in the process industries. Low-cost options include:

  • dual outputs
  • programmable alarms
  • remote setpoint
  • RS485 communications
  • analog retransmission
  • digital input
  • timer function
  • heater burnout alarm
  • 24V AC/DC supply voltage

A large LED display is one of the most impressive features. The faceplate, designed for NEMA 4X (IP66 equivalent), is watertight and resistant to corrosion. The easy-to-use 3-button keypad allows for programming, similar to the popular PXW controller. The screw-terminal on the back eliminates the need for sockets, reducing the cost even more. The PXR3 can be DIN-rail mounted with the optional adapter.

With the RS485 option, remote monitoring of up to 31 controllers at a time is possible using the industry-standard Modbus™ protocol. The communications option comes
with our free Windows-based software, PXR-LITE™. This software allows you to program the controller from the PC and view real-time data and trend graph while logging the data into a text file.

The Program Loader option, with Windows®-based software, is a powerful tool for the OEM customer. Programs for different applications can be saved to and from the controller.
