Features

  • Loop power supply: 17.5 V ±1 V bei 20mA open circuit voltage: 24.5 V ±5%
  • Input signal range (underrange/overrange): 0 to 22mA feeding/not feeding
  • Output signal range (underrange/overrange): 0 to 22mA active/passive
  • Maximum temperature change rate 0.5°C/min, no condensation permitted
  • Ambient temperature range: -40 to 140°F (-40 to 60°C)
  • Intrinsic safety for operation in hazardous areas (Zone 2)

The 1- or 2-channel E+H RN22 active barrier powers analog instrument loops and safety instrumented systems up to SIL 2 (SC 3). The intrinsically safe, HART® transparent interface establishes a link between field devices and process control. It interfaces with 2-/4-wire devices in hazardous areas and provides a second galvanically isolated signal output acc. to NAMUR NE 175. This opens a second channel for the process optimization domain without affecting the traditional automation system. No manual hardware settings are required at the device for commissioning.

The RN22 active barrier allows for separation of 0/4 to 20 mA standard signal circuits, optionally available as a signal doubler. The device can be configurated for screw or push-in terminals, or power supply via power rail T-connector. Compact housing also allows for up to two channels on 12.5 mm (0.49 in). Additionally, the connection lugs are integrated on the front for HART® communicators.
