Switch Amplifier
Description
1-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Passive transistor output, non-polarized, Passive fault output, non-polarized, Line fault detection (LFD), Reversible mode of operation, Up to SIL 2 acc. to IEC 61508pa. This isolated barrier is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. The proximity sensor or switch controls two passive transistors for the safe area load. The normal output state can be reversed using switch S1. Switch S2 allows output II to be switched between a signal output or an error message output. Switch S3 enables or disables line fault detection of the field circuit. During an error condition, the transistors revert to their de-energized state and LEDs indicate the fault according to NAMUR NE44. Eine Sammelfehlermeldung ist möglich, wenn das Gerät über Power Rail betrieben wird.
