PXR Series
Advanced Self-Tuning Temperature and Process Controllers
FUJI PXR SERIES CONTROLLERS
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.
Key Features
Key Features
• Description
• PID with fuzzy control of self-tuning
• 16 Ramp/soak segments
• Large LED display
• Digital input
• Auto-tune
• Timer function
• Heater burnout alarm
• Replaces most other controllers
in market
• Excellent for after-market support
They come in several sizes – 1/32 DIN, 1/16
DIN, 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, it now comes 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
TM
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

software. Programs for different applications
can be saved to and from the controller.
