Type
Electronic pressure switch with display (model PSD-4)
Fits electronic pressure switching with display where you need a WIKA PSD-4. Pressure switch spanning gauge and absolute ranges up to about 1000 bar / 14500 psi class, switch-point accuracy ≤±0.5% of span, PNP/NPN switching (1 or 2) and/or 4–20 mA or 0–10 V analogue with IO-Link 1.1, on DC 15–35 V.
Key advantages
- Ranges — Gauge/absolute to ~1000 bar class
- Accuracy — Switch-point ≤±0.5% of span
- Outputs — PNP/NPN and/or 4–20 mA / 0–10 V
- IO-Link — Version 1.1
- Supply — DC 15–35 V
Typical applications
- Machine pressure switch.
- Hydraulic discrete/analogue.
- IO-Link pressure points.
Selection guide
- Range / process connection
- Output set
- IO-Link need
Common mistakes
- Wrong range for OPL.
- Supply outside 15–35 V.
- Ignoring switch-point accuracy.
When to RFQ / what to tell us
- Range/output/connection.
- Quantity, ship-to.
