Field of application
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
Galvanic isolation (3-way)
Line fault monitoring of input circuits or mechanical switching contacts
Group error message via DIN rail bus connector
Output-side relay contacts, direction of action (operating or quiescent current behavior) via DIP switch selection
Ambient temperature range: –40 to 60 °C (–40 to 140 °F)
