Signal Isolator - SI139
The SI139 converts DC current or volts to DC signals, and features:
- Input up to 2kVdc and 10Adc.
- Input options for AC current & voltage up to 500V span and true rms (not sine wave).
- Input options for bi-polar dc current & voltage.
- Output up to 18Vdc or 50mAdc.
- 2000Vrms isolation.
- Designed for single (factory set) input/output combinations.
- Front adjustments for span and zero.
- All common AC or DC supplies.
- Sensor excitation.
- Options include adder/subtractor, min/max select, track & hold, peak-hold and ratio adjust.
Common applications include:
- Signal conversion of DC signals.
- Prevention of ground and current loops.
- Protection from dangerous floating voltages.
- Filter of common mode noise
