Details

The RN221N supply isolator from Endress+Hauser supplies e.g. a transmitter, if necessary also in hazardous areas, and transmits the signal galvanically isolated. With the optionally available HART® monitoring, the status of the transmitter is monitored. If an error occurs, a relay switches on the RN221N. The relay must be actively reset. This makes it easy to locate faults that only occur for a short time.
