Fuji Electric PXF4 Temperature Controller

Fits panel temperature or process loops that need a 48×48 mm (1/16 DIN) controller with universal RTD / thermocouple / voltage-current input, fast 50 ms sampling, and configurable control / retransmission outputs.

Key advantages

1/16 DIN (48×48) — Compact PXF4 panel size in the PXF family.
Universal input — RTD, thermocouple, voltage/current process value.
50 ms sampling — Fast PXF-series sample time.
Flexible outputs — Relay / SSR / current / voltage / motorized valve; retransmission options.
Up to 3 alarms + RS-485 — Alarm and communication options by order code.

Typical applications

Compact panel temperature control in 1/16 DIN cutouts.
Process loops needing fast sampling with relay or SSR control.
PXR7 replacement projects using ZZP panel adapters to PXF4.

Selection guide

Input — Universal: RTD, thermocouple, voltage/current. Confirm sensor type and range on the order code.
Sampling — 50 ms (PXF series). Request the datasheet accuracy table for your input type when quoting.
Control / outputs — Relay / SSR / current / voltage / motorized valve; retransmission 0–20 mA, 4–20 mA, 0–5 V, 1–5 V.
Alarms — Up to 3 alarm outputs on PXF4.
Communication — RS-485 option; multi-drop master function.
Display — Color LCD type available.
Mounting — 48×48 mm (1/16 DIN) panel mount; socketed variant is a separate SKU.
Supply — Per order code — lock available panel voltage before ordering.
Replacement note — Panel adapter ZZP… for PXR7 → PXF4 replacement.

Common mistakes

Ordering PXF4 when the panel cutout is PXF5/PXF9 size — this SKU is 48×48 mm (1/16 DIN) only.
Leaving supply voltage blank — supply is per order code.
Specifying three alarms or RS-485 without confirming those options on the model code.
Assuming socketed mounting is included — socketed variant is a separate SKU.
Inventing IP / ambient / approval numbers not locked on the order code — pull from the full datasheet for the chosen suffix.

When to RFQ / what to tell us

Sensor type/range, control output type, and alarm/RS-485 options.
Panel supply voltage, display preference, PXR7-replacement adapter need.
Quantity, ship-to; full model code if known.

FAQ

Q: Is PXF4 the right DIN size? A: PXF4 is 48×48 mm (1/16 DIN) panel mount. PXF5/PXF9 are covered in the same family brochure but are different sizes — confirm cutout before ordering.

Q: What outputs can I get? A: Control options include relay, SSR, current, voltage, and motorized valve; retransmission 0–20 mA, 4–20 mA, 0–5 V, 1–5 V. Up to 3 alarms on PXF4. RS-485 is optional.

Q: Can I replace a PXR7 with PXF4? A: Datasheet notes panel adapter ZZP… for PXR7 → PXF4 replacement. Say so in the RFQ with the existing cutout and wiring.

Q: What should I send for a quote? A: Input type/range, output mix, alarms, RS-485, supply, quantity. Compatible with systems using Fuji Electric PXF4 if you need a drop-in check — we do not claim authorized-dealer status. IP / ambient / approvals are blank in our checked data; ask if you must match specific marks.
