What are the differences between independent powered, loop powered and output loop powered?

Independent powered

The isolated barrier requires independent 24V power supply.

Loop powered

There is no need for an external power supply. The signal acquisition loop and the power distribution loop share one loop.

Output loop powered

The output is loop powered. It outputs passive signals, which need DCS/PLC to provide external power supply.
