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
