Endress+Hauser RN221N-C3

Active Barrier w/Optional HART Diagnosis, NAMUR NE 43

See our Endress + Hauser RN221N Active Barrier Family Page for an ordering guide and all configurations.
The active barrier RN221N supplies e.g. a transmitter with power, if required also in the Ex-area, and then transmits the galvanically isolated signal. With the optionally available HART® monitoring the status of the transmitter is monitored. If an error arises a relay at the RN221N sends an alarm. The relay has to be actively set back. Thus even just briefly occurring errors can be easily located.
