Isolated Converter
Key features

Isolation and conversion of standard DC signals
Slimline housing of 6 mm
Power supply and signal isolator for 2-wire transmitter
Loop supply >17 V
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.
Installation in ATEX Ex zone 2 / IECEx zone 2 / FM division 2.
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.
