Temperature & Process Controllers PXR Series
Fuji Electric PID Controllers with Fuzzy Control of Self-Tuning
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 features and options and come in several sizes — 1/32 DIN, 1/16DIN, 1/8 DIN and 1/4 DIN.
These controllers have all the standard features that you expect from Fuji Electric’s superior controllers, and more. In addition to auto-tuning and fuzzy control, they now come with self-tuning — an innovation in the control field. It 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 PXR 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.
Low-cost options include dual outputs, programmable alarms, remote setpoint, RS485 communications, analog retransmission, digital input, timer function, heater burnout alarm and 24V AC/DC supply voltage. One of the most impressive features 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 Modbus™ protocol. The communications option comes with our free Windows®-based software, PXR-LITE™. The 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. 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.
