The SI239 converts DC current or volt to DC signals, and features:
- 2-wire or 3-wire output loop power supplies.
- Inputs signals up to 2000Vdc and 10Adc.
- Input option for true rms (not sine wave).
- 2000Vrms isolation.
- Designed for single (factory set) input/output combinations.
- Front adjustments for span and zero.
- Options include adder/subtractor and min/max select.
Common applications include:
- Signal conversion for use with PLC's.
- Prevention of ground and current loops.
- Protection from dangerous floating voltages.
- Filter of common mode noise
