The RLN22 is a compact 1- or 2-channel, 24 VDC isolating amplifier with relay signal output. It is designed to safely operate e.g. proximity sensors or point level switches such as the Liquiphant FTL51B (NAMUR) as per IEC 60947-5-6. The DC interface monitors line faults such as breaks or short-circuits of sensors or mechanical switching contacts. The device is suited for use in hazardous areas and safety instrumented systems up to SIL 2 in accordance with IEC 61508.
Isolating amplifier for the transmission of binary switching signals
Input for proximity sensors, open contacts or contacts with resistive coupling elements
