Field of application

The RN42 is a 1-channel active barrier with wide range power supply for safe isolation of 4 to 20 mA standard signal circuits, HART-transparent. The device has an active / passive current input to which a 2- or 4-wire transmitter can be connected directly. The output of the device can be operated actively or passively. The current signal is then available to the PLC / controller or for further instrumentation at pluggable screw or optional push-in terminals.

Features

  • Active barrier, wide-range power supply
  • 1-channel
  • Compact housing
  • Quick and easy wiring
