Isolated repeater / splitter
3108
- Isolation and conversion of current signals
- Slimline housing of 6.1 mm
- Response time <7 ms
- Splitter function: 1 in - 2 out
- Simple - no setup needed
Application
- Isolation and conversion of standard DC signals.
- Galvanic separation of analog current signals.
- Elimination of ground loops and measurement of floating signals.
