Product Overview
The Aplisens ZS-30 Power Supply & Isolator is used for two-wire 4–20 mA transmitters and supports a universal supply of 20–253 V AC/DC. For accurate selection and pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens ZS-30 is a power supply and signal isolator designed to power two-wire transmitters with a 4–20 mA output and to transform the signal through full galvanic separation into standard control signals. Circuits IN, OUT, and SUPPLY are galvanically separated.
- Universal power supply: 20–253 V AC/DC
- Full galvanic separation: IN–OUT, IN–SUPPLY, OUT–SUPPLY
- Digital calibration of the measurement chain IN–OUT
- Accuracy: 0.1%
- Standard output: 4–20 mA (other outputs available)
Need a special output type (0–10V, 1–5V, 0–20mA, etc.)? We can help confirm the correct ZS-30 configuration.

ZS-30 provides galvanic isolation between IN/OUT/SUPPLY circuits for improved noise immunity and safety.
ZS-30 pricing depends on the output configuration. To quote correctly, we typically confirm:
| What We Need | Examples |
|---|---|
| Output Type | Standard 4–20 mA or special output: 0–10V, 1–5V, 0–20mA, 0–5mA |
| Receiving Load (RO) | Confirm the input/load resistance of your PLC/DAQ/controller to match the selected output |
| Power Available | Confirm available supply: 20–253 V AC/DC |
Ordering: ZS-30 = standard (Iout = 4–20 mA). Special version format: ZS-30/___ (specify output type). Call 865-900-8844 or email KSmith@CPSCalibrations.com.
