Intrinsically safe 24 VDC compact interface module for use in hazardous areas, SIL systems

The 1- or 2-channel 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 reliable 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.
