The Endress+Hauser RLN22 is a compact 24 V DC isolating amplifier for the transmission of binary switching signals. 1- or 2-channel isolation amplifier with relay signal output, 3-way galvanic isolation. The monitoring of input circuits for line faults such as breakage and short-circuit (LFD) of sensors is disengageable. Input for proximity sensors according to NAMUR (EN60947-5-6) and open contacts or contacts with resistive coupling elements. Line fault monitoring of input circuits or mechanical switching contacts. Output-side relay contacts, direction of action (operating or quiescent current behaviour) via DIP switch selection. Group error message via DIN rail bus connector at power and error message module.
