The SI231 is an isolated loop-powered signal converter for common process signals, and features:
- Field configurable inputs 4-20mA, 0-1mA, 0-10mA, 0-20mA, 0-1V, 0-2V, 0-5V, 1-5V & 0-10V.
- 2-wire or 3-wire output loop power supplies.
- 2000Vrms isolation.
- Field configurable response time.
- Front adjustments for span and zero.
Common applications include:
- Signal conversion for input to PLC's.
- Prevention of ground and current loops.
- Protection from dangerous floating voltages.
- Filter of common mode noise
