FUJI PXR4 PID Controller
Product Code : PWHT-7048
FUJI PXR4 PID Controller
The PXR4 is a 1/16 DIN (48mm x 48mm) is our most popular controller. It is compact, easy to use and with a large and bright LED display.
In addition to auto-tuning and fuzzy control, Fuji PXR4 temperature controllers now come with self-tuning - an innovation in the control field. Self-tuning automatically re-tunes the controller under certain conditions, without the need to revert to auto-tuning.
Delivery Ex-stock for most variations
Input types, thermocouple, RTD, 1-5Vdc and 4-20mA
Output types, relay contact, SSR/SSC and 4-20mA
On/off control, PID with auto-tune & Fuzzy control as standard
Fuzzy control eliminates overshoot & reduces external disturbance
Sixteen types of alarm with one or two relay contact outputs
Setpoint ramping, dual PID heating/cooling and heater break alarm
Power supply 24Vdc, 24Vac or 100-240Vac
Weatherproof front panel IP66
The PXR4 accepts any probe type as an input (thermocouple, RTD, 1-5Vdc and 4-20mA need to be specified prior to delivery) and can control any type of device with 6 types of output available (relay contact, SSR/SSC, 1-5V 0-10V and 4-20mA).
It is simple enough to be used for basic "ON/OFF" applications with minimum set-up thanks to the auto-tuning feature.
The Fuji PXR temperature controller accepts process and temperature 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.
