The Endress+Hauser RN22 is a 1- or 2-channel active barrier, power supply or signal doubler for safe separation of 4 to 20 mA standard signal circuits. The device safely powers analog instrument loops and safety instrumented systems up to SIL 2, SC 3 (according to IEC 61508). The HART transparent interface device establishes a reliable signal link between field devices and process control. It interfaces with 2 or 4 wire instruments in Zone 2 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.
