The Fuji controllers in the 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 (Fuji PXR3), 1/16 DIN (Fuji PXR4),
1/8 DIN (Fuji PXR5), and 1/4 DIN (Fuji PXR9). In addition to
auto-tuning and fuzzy control, these Fuji controllers 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 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 these Fuji
controllers 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 Fuji 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-LITE™. 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. |
