Key features

Isolation and conversion of standard DC signals
Slimline housing of 6 mm

Low cost
DIP-switch configured 


Isolation and conversion of standard DC signals.

Galvanic separation of analog current and voltage signals.

Elimination of ground loops and measurement of floating signals.

A competitive choice in terms of both price and technology for galvanic isolation of current and voltage signals to SCADA systems or PLC equipment.

Suitable for environments with high vibration stress, e.g. ships.


Easy configuration via DIP-switches.

The input is protected against overvoltage and polarity error.

Factory-calibrated measurement ranges.

Inputs and outputs are floating and galvanically separated.
