Knick loop-powered isolators for 0 … 20 mA signal transmission. These modules are available as hazardous-area input and hazardous-area output isolators. Due to their patented design (German patent 3526997), they are considered to be the most reliable solution for isolating standard signals without an external power supply.
The IsoTrans 36 and 37 isolators are not only suitable as highly reliable isolators for normal applications, they also meet the most stringent requirements that can be set for potential isolation. There is no need for power supply wiring.
