Endress+Hauser 2 Channel Zener Barrier


Intrinsically safe active barrier that provides power and safety to analog instrument loops and SIL systems, establishing a reliable signal link between field devices and process control level.

The 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.

Connection lugs integrated on front for HART communicators

Simple and quick wiring with plug in terminals
