RN221N
Active barrier with optional HART® diagnosis

Active barrier with power supply for safe separation of 4...20 mA current circuits

  • Active barrier RN221N ©Endress+Hauser
  • Active barrier RN221N ©Endress+Hauser

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.
