Field of application

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.

Single- or two-channel active barrier, power supply or signal doubler
0/4 to 20 mA analog signal transmission (NAMUR NE 43) and galvanic isolation
Intrinsic safety for operation in hazardous areas (Zone 2)
Bidirectional HART® communication (transparent)
2- and 4-wire capability for instruments in hazardous areas (Zones 0/20)
Ambient temperature range: -40 … 60 °C (-40 … 140 °F)

Benefits

Intrinsically safe interface device suited for use in safety instrumented systems up to SIL 2 (SC 3) in accordance with IEC 61508
Quick and easy wiring with screw or push-in terminals or power supply via power rail T-connector
Easy access to frontside HART® connection taps
Compact housing: up to two channels on 12.5 mm (0.49 in) for efficient use of space in control cabinets

Success stories

Functional Safety in practice

Investments in functional safety, and thus in measures to avoid accidental and systematic errors, are very moderate if one relies on instruments developed according to IEC 61508.
