Opis
2-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Usable as signal splitter (1 input and 2 outputs), 2 x 2 relay contact outputs with AND logic, Reversible mode of operation, Line fault detection (LFD), Up to SIL 2 acc. to IEC 61508pa. This isolated barrier is used for intrinsic safety applications. The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area. Each input controls a relay contact output. Via switches the mode of operation can be reversed and the line fault detection can be switched off. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
