The RLN22 is a compact 24 V DC isolation amplifier for transmission of binary switching signals. 1- or 2-channel isolation amplifier with relay signal output, galvanic 3-way-isolation. The monitoring of input circuits for line faults such as open-circuit and short-circuit (LFD) of sensors can be switched off. Input for proximity switch according to NAMUR (EN60947-5-6) and open contacts or contacts with ohmic coupling elements. Cable fault monitoring of input circuits or mechanical switch contacts. Output-side relay contacts, direction of effect (working or quiescent current behavior) can be selected via DIP-switch. Group fault reporting via DIN rail bus connector on the power and fault signaling module.This text is machine translated.
