Switch Amplifier
Description
2-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Isolated passive transistor 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. Each proximity sensor or switch controls a passive transistor output for the safe area load. Both transistor outputs are isolated from each other and isolated from the power supply. The normal output state can be reversed using switch S1 for channel I and switch S2 for channel II. 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.
