No power supply required
Cost savings due to lower wiring effort, no mains interference
Very low residual ripple
No interference of the connected measuring or control system
Explosion protection according to ATEX
High transmission accuracy
Excellent pulse formation due to exact transmission of the measured values
Very low common-mode interference
Prevention of incorrect measurements or failures caused by interference
Maximum reliability
No repair or failure costs
10 kV test voltage
(optional)
Protective separation according to EN 61140
Protection of the maintenance staff and subsequent devices against excessively high voltages
SMART transmission
Bi-directional point-to-point transmission of digital data according to the HART specification
5-year warranty

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 37A7 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.
