Endress+Hauser RN22 RN22-8L2BPA Feed/input isolation amplifier 1 pc(s)

The RN22 is a 1- or 2-channel active barrier, power supply or signal doubler for safe isolation of 4 to 20 mA standard signal circuits. It supplies safely analog measuring loops and safety-related systems up to SIL 2, SC 3 (according to IEC 61508). The transparent HART® interface device provides a reliable signal connection between field devices and the HER process control system. It offers an interface to 2 or 4-wire devices in hazardous areas of zone 2 and provides a second, galvanically isolated signal output according to NAMUR NE 175. This opens a second channel for process optimization without affecting the traditional automation system.
