3109

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.
