RN22-CB1B

RN22-CB1B is a RN22 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 analogue 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.

• Active barrier for safe separation of standard signal circuits
• Compact housing
• Quick and easy wiring
• Intrinsic safety for operation in hazardous areas (Zone 2)
• For safety-oriented applications up to SIL 2 (SC 3) in accordance with IEC61508 (optional)
