Fuji Electric PXR3 Temperature Controller

Fits compact 24×48 mm panel temperature control where you need universal TC/RTD/1–5 V input, PID auto-tune, and IP66 / NEMA 4X front sealing.

Key advantages

24×48 mm compact — panel temperature controller with large 11 mm LED digits.
Universal input — TC / RTD / 1–5 V DC field-selectable with PID auto-tune.
IP66 / NEMA 4X front — washdown-capable panel face.
Flexible I/O — relay/SSR/current control; optional RS-485 Modbus or Z-ASCII; up to 2 alarms.

Typical applications

OEM panels needing a small 24×48 mm temperature controller.
Retrofits replacing compact PID loops with universal TC/RTD input.
Machines optionally adding RS-485 for supervisory polling.

Selection guide

Input — Thermocouple / RTD / 1–5 V DC universal input (field-selectable per OEM documentation tables).
Accuracy — Per PXR3-2 OEM input accuracy tables (typically ±0.5% FS class depending on input).
Output — Control output relay/SSR/current options; optional retransmission; alarm up to 2 points; heating/cooling version available.
Supply — 100 V (−15%) to 240 V (+10%) AC 50/60 Hz or 24 V (±10%) AC/DC.
IP / front — Front NEMA 4X / IP66 watertight.
Display — Large LED, 11 mm character height.
Communication — Optional RS-485 (MODBUS or Z-ASCII).
Mounting — 24×48 mm panel mount.
Approvals — NEMA 4X front; UL/cUL (model-dependent — verify datasheet).
Notes — Micro-Controller X PXR3. PID auto-tuning/self-tuning/fuzzy; optional 8-step ramp/soak, digital inputs, timer. PXR4/5/7/9 discontinued → PXF; PXR3 remains.

Common mistakes

Ordering 24 V supply when the panel only has line voltage (or the reverse).
Assuming UL/cUL on every code — marks are model-dependent.
Specifying RS-485 without choosing MODBUS vs Z-ASCII.
Confusing this Micro-Controller X PXR3 with the separate Digital Thermostat PXR3 variant.
Expecting larger DIN sizes — this face is 24×48 mm only.

When to RFQ / what to tell us

Input sensor/process type (TC type, RTD, or 1–5 V) and control action (heat / cool / duplex).
Control output type (relay / SSR / current), retransmission, and alarm count.
Supply (100–240 VAC or 24 V AC/DC) and RS-485 need.
Ramp/soak or timer requirements; quantity; ship-to country.
Compatible with Fuji Electric PXR3 panel cutouts — we do not claim authorized-dealer status.
