Function: S1SL-2AI-2C

This signal conditioner provides the galvanic isolation between field circuits and control circuits.

The device transfers a 0/4 mA ... 20 mA signal of a current source from the field side to the control side.

This device is loop powered. No additional power supply has to be connected.
