RN221N Active barrier with optional HART® diagnosis

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

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.

Condition: Used

Order Code: RN221N-D1
