Switch Amplifier
Description
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. 1-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Active transistor output, Active fault output, Line fault detection (LFD), Reversible mode of operation, Up to SIL 2 acc. to IEC 61508pa. The proximity sensor or switch controls an active transistor output per channel for the safe area load. The normal output state is reversed using switch S1. Switch S2 allows output II to be switched between a signal output and 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. A unique collective error messaging feature is available when used with the Power Rail system.
