Signal Isolator - SI231

Signal Isolator - SI231

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 loop power or 3 wire output
• 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
