Fuji
Electric PXR4 Self Tuning Temperature/Process Controller
The Latest Self-Tuning Temperature/Process Controller:
Fuji Electric’s PXR4 Controller With Improved, Larger LED
Display
New and improved features highlight the latest controller
from Fuji Electric, the PXR4. This 1/16 DIN Temperature
Controller includes an LED display that is 1.6 times larger
than other previous models with a dust-proof front display
and operational section that is waterproof and conforms
to NEMA-4X (IP66).
Both auto-tuning and the more advanced, self-tuning functions
calculate optimum PID parameters. Fuzzy control is a standard
feature suppressing overshoot without lengthy start-up time
and improving the response to external disturbances by quickly
reverting to set points. A standard feature included in
the PXR4 is the 16-segment ramp/soap function.
The digital input option that can be added to the PXR4 allows
the operator to remotely change between two setpoints, start/stop
the control action, start/reset the ramp/soak, start/stop
the autotuning, cancel the alarm latch, or start the incorporated
timer. The PXR4 Controller offers additional options such
as: timer function, heating/cooling control, heater burnout
alarm, and the free, standard 16-segment ramp/soak function
feature. Relay, SSR driver and 4-20 mA outputs may be chosen.
The PXR4 accepts temperature and process inputs, and offers
two control output alarms and two programmable alarms.
Daisy-chaining up to 31 controllers on an RS 485 network
is an option with the PXR4. Using a PC, the operator is
then able to monitor all 31 controllers via the industry
standard Modbus™ communications protocol.
The PX Fuzzy
Logic Controllers series
also offers a wide range of choices for your unique space
requirements and programming preferences.
