The Aplisens ZS-30/1Ex is an intrinsically safe power supply and isolator designed to power intrinsically safe two-wire transmitters in hazardous areas with a 4–20 mA signal, and to transform that signal through a galvanic separation circuit into standard control signals. The IN, OUT, and SUPPLY circuits are galvanically separated.
- Ex-rated intrinsically safe (hazardous area transmitter interface)
- Universal power supply: 20–253 V AC/DC
- Full galvanic separation: IN–OUT, IN–SUPPLY, OUT–SUPPLY
- Digital calibration of measurement chain IN–OUT
- Accuracy: 0.1%
- DIN rail mounting: TS35 / TS32
Standard version provides an intrinsically safe input circuit supply of 24 VDC. Special versions are available for different output signals.

For hazardous areas: ZS-30/1Ex provides an intrinsically safe input circuit for the transmitter and galvanic isolation between circuits.
ZS-30/1Ex pricing depends on 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 your PLC/DAQ/controller input/load matches the selected output resistance requirements |
| Hazardous Area Use | Confirm transmitter type and area classification so we can help validate the correct Ex application |
Ordering procedure: Standard version (UIN = 24 V, IOUT = 4–20 mA) is ZS-30/1Ex. Special version format: ZS-30/1Ex /___ (specify output signal). Call 865-900-8844 or email KSmith@CPSCalibrations.com.
