We sell Pepperl+Fuchs switch amplifier KCD2-SR-Ex2.
Time: 2020年08月07日Switch amplifier KCD2-SR-Ex2: 2-channel isolated barrier, 24 V DC supply (Power Rail), Dry contact or NAMUR inputs, Relay contact output, Line fault detection (LFD), Housing width 12.5 mm, Up to SIL 2 acc. to IEC 61508.
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 a form A normally open relay contact 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 and an error message output. Switch S3 enables or disables line fault detection of the field circuit.
During an error condition, relays 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.
Due to its compact housing design and low heat dissipation, this device is useful for detecting positions, end stops, and switching states in space-critical applications.
