The SMC ZSE20(F) ISE20 digital pressure switch user manual provides safety guidelines, installation, wiring, configuration and specifications.
This manual covers safety precautions, model designation, and a detailed description of each part of the digital pressure switch. It explains terminology, installation steps, pipe and wiring methods, and the various configuration options available for both ZSE20(F) and ISE20 models.
The document also includes setting procedures for pressure ranges, function‑selection modes, factory defaults, maintenance tips, a fault list, and full technical specifications such as pressure ranges, output limits, operating temperature and data retention. This manual is written in Chinese.
| Pressure range (positive pressure, ISE20) | -0.100 ~ 1.000 MPa |
|---|---|
| Pressure range (vacuum, ZSE20) | 0.0 ~ -101.0 kPa |
| Pressure range (mixed, ZSE20F) | -100.0 ~ 100.0 kPa |
| Maximum output voltage | 28 V |
| Maximum output current (NPN) | 80 mA |
| Maximum output current (PNP) | 80 mA |
| Data write cycles | 10 000 cycles |
| Data retention period | 20 years |
| Operating temperature range | -5 °C ~ 50 °C |
Select the measurement mode in the configuration menu and choose the appropriate pressure range (‑100 kPa to 100 kPa) for the ZSE20(F) model.
The device can output up to 28 V with a maximum current of 80 mA for both NPN and PNP output types.
For M5 threads tighten by hand then add 1–1.5 Nm with a wrench; for larger threads use 3–5 Nm as specified.
