RN221N

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

Highlights
  • Compact side by side DIN rail housing
  • Bidirectional HART® transmission
  • Input 1 x analog 4...20 mA
  • Output 1 x analog 4...20 mA
  • Relay output 1 x no contact
  • Auxiliary power supply / Loop power supply 20...250 V DC/AC
Product Description

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.

Fields of application
  • 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
  • Intrinsically safe sensor supply for Ex-area
