Product Overview
The Aplisens SP-02 Current Signal Isolator provides galvanic isolation for 0/4–20 mA loops and operates without auxiliary power (two-wire loop powered). For accurate selection and pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens SP-02 is a current signal isolator designed to provide galvanic separation between measurement circuits installed on equipment and the main control section. It isolates and transfers a 0/4–20 mA signal to a matching 0/4–20 mA output and is loop powered (no auxiliary power required).
- Signal in/out: 0/4–20 mA (loop powered)
- No auxiliary power: powered from the input signal loop
- Accuracy: ±0.16% (typical)
- Single or dual circuit: 12.5 mm wide housing
- DIN rail mounting: TS35 / TS32
- Isolation: transformer-based galvanic separation
Typical use: eliminate ground loops and object-related interference in monitoring, control, and recording systems.

SP-02 pricing depends on configuration. To quote correctly, we typically confirm:
| What We Need | Examples |
|---|---|
| Number of Circuits | 1 circuit or 2 circuits |
| Signal Type | Standard 0/4–20 mA in/out (loop powered) |
| Special Output (if needed) | Optional version with 0–10 V voltage output |
| Receiving Load | Confirm your controller input and loop load to stay within 0–500 Ω |
Ordering format:
Standard: SP-02 /___ (number of circuits: 1 or 2)
Special (0–10 V output): SP-02 / 0...10 V /___ (number of circuits: 1 or 2)
