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. Specs at a glance Input 1 x analog 4...20 mA Output 1 x analog 4...20 mA Power Supply Not defined
