Current signal isolator without auxiliary power

---------------------

Manufacturer: Aplisens(Poland)

Model:  SP02 Series

Application:

The SP-02 signal  isolator  provides galvanic  separation  of an input signal (0/4...20 mA) and converts it, through a separation system into an output signal (0/4...20 mA), with a two-wire power supply in the input signal loop. The device is typically  used to provide galvanic separation be-tween the measurement circuits installed on an object, and the main section. This enables the effect of object-related interfer-ence in  the monitoring, control and recording systems of auto-matic devices to be largely eliminated.

Specification:
