Področje uporabe

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.

  • Galvanic isolation of 4 to 20 mA current circuits

  • Removing large loop circuits

  • Powering 2 wire transmitters

  • Monitoring of SMART transmitters with early-warning system
