Fuji Digital Temperature Controller is a digital temperature controller produced by Fuji company, which has ON/OFF control, auto-tuning, self-tuning, alarm function, etc.
This manual provides detailed guidance for installing, wiring, and operating the Fuji Electric PXR3 digital temperature controller. It includes safety precautions, mounting instructions, wiring diagrams, and configuration steps for temperature and parameter settings.
The document also lists the controller's technical specifications, communication options (RS‑485 Modbus and Z‑ASCII), input/output capabilities, and recommended environmental conditions for reliable performance.
| Power voltage | 100 (-15%) to 240 (410%) V, 50/60 Hz |
|---|---|
| Power consumption | 6 VA or less (100 V AC), 8 VA or less (240 V AC, 24 V AC/24 V DC) |
| Relay contact output | SPST contact, 220 V AC/30 V DC, 3 A (resistive load) |
| SSR/SSC driving output voltage (PXR3) | 15 V DC |
| 4‑20 mA DC output maximum current | 20 mA or less |
| Communication interface | RS‑485 Modbus and Z‑ASCII |
| Number of inputs | 2 inputs maximum |
| Operating ambient temperature | -10 °C to 50 °C |
The controller should be installed in an environment with operating temperature from –10 °C to +50 °C, humidity up to 90 %RH (non‑condensing), installation category II, and pollution degree 2.
The PXR3 controller supports up to two input channels.
The controller provides RS‑485 Modbus and Z‑ASCII communication interfaces.
Use independent safety equipment with a separate temperature sensor, keep ventilation openings clear, and do not block the controller’s openings or radiation paths.
