The controllers in the Fuji Electric PXR Series are the latest additions to Fuji Electric’s trusted line of process and temperature controllers. Controllers in this series come in several sizes: 1/32 DIN (PXR3), 1/16 DIN (PXR4), 1/8 DIN (PXR5), and 1/4 DIN (PXR9). In addition to auto-tuning and fuzzy control, this series now 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 has been expanded to include two patterns that can be linked to create a 16-step profile.

The Fuji Electric PXR Series accepts temperature and process inputs and offers a choice of three kinds of outputs to meet a wide variety of needs in the process industries. Single or dual outputs include relay, SSR driver, or 4-20mA.

One of the most impressive features of the controllers in the Fuji Electric PXR Series is the large LED display. The faceplate, designed for NEMA 4X (IP66 equivalent) is watertight and corrosion-resistant. The easy-to-use 3-button keypad allows for programming similar to the popular PXW controller. The screw-terminal on the back further reduces the cost by eliminating the need for sockets. The PXR3 can be DIN-rail mounted with the optional adapter.

Remote monitoring of up to 31 controllers at a time is possible with the RS485 option that uses the industry-standard ModbusTM protocol. The communications option comes with our free Windows®-based software, PXR-LITETM. The software allows you to program the controller from the PC and view real-time data and trend graph while logging the data on to a text file.

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

In addition, low-cost options available to the Fuji Electric PXR Series include dual outputs, programmable alarms, remote setpoint, RS485 communications, analog retransmission, digital input, timer function, heater burnout alarm and 24V AC/DC supply voltage. The digital input option allows the user to change between 2 setpoints, change between ramp/soak and standby, start/reset the ramp/soak, start/stop the auto tuning, cancel the alarm latch, and start the incorporated timer.
