DATA SHEET
PYX4
The PYX is a state-the-art temperature controller offering
enhanced control through the use of fuzzy logic. By em-
ploying fuzzy logic the PYX virtually eliminates system
overshoot and effectively supresses fluctuation of the
process variable due to external disturbances. Fuzzy logic
control is the technology of tomorrow offered today.
This controller features universal input circuitry and can
accept signals from all thermocouple types, RTD's, and
current/voltage sources. As well, the PYX-4 gives you the
flexibility of choosing such available features as RS-485
communications, analog retransmission, dual output, heater
break alarm, and loop break alarm, to name a few. The
PYX-4 is the world's first 1/16 DIN fuzzy logic controller
featuring high performance/cost ratio.
FEATURES
1. Industry-first incorporation of fuzzy control in 48 mm-
square controller
An improved response characteristic of controller is
ensured thanks to the fuzzy control exercised while
detecting an overshoot or a difference from the set
temperature value due to a large disturbance.
(Time taken for returning to the set value can be shortened
and temperature variation width can be narrowed.)
2. Universal input
This means that a signal controller can respond to 11 kinds
of thermocouples, resistance bulbs and voltage/current
inputs.
3. Communication function comprised despite small size
(option)
Because the general-purpose interface (RS-485) is
mountable, a centralized monitoring/setting system aided
by a personal computer can readily be configured. Upon
building up a system, the size of this controller as small
as 48 mm square is helpful for saving on the equipment
installation area.
The communication protocol conforms either the Fuji
Electric CC data line or Modbus® RTU.
4. Auto/Manual
Change auto-mode to manual-mode and manual operation
can be done using front panel keys.
5. A wide variety of optional functions
(1) A0 re-transmission (1 point)
A0 is recordable in connection with Fuji's microjet
recorder PHA/PHC.
(2) Programmable alarm (2 points max.)
2 kinds of alarm action can be registered selected
from 16 kinds.
(3) Dual output
Dual control of heating and cooling operations are
allowed
(In this case, communication, A0 and HB (heater
break) functions cannot be added).
(4) Heater break alarm
Use ALM1 or ALM2 output for heater break alarm
(with heater current message-function)
(5) Ramp/soak function
4 ramp/soak-pair patterns are registrable.
(6) External DI function (1 point)
SV (setting value) can be changed a predetermined
value according to external command input (DI).
(7) Remote SV
SV (setting value) can be controlled by external 1 to
5V DC analog input.
6. UL, C-UL approval
Modbus® is a registered trademark of Gould Modicon.
