Switch Amplifier KCD-SR-Ex.LB Features Assembly -channel isolated barrier V DC supply (Power Rail) Dry contact or NAMUR inputs Usable as signal splitter ( input and outputs) Relay contact output Fault relay contact output Line fault detection (LFD) Housing width.5 mm Up to SIL acc. to IEC 6508 Front view KCD-SR- Ex.LB PWR OUT/CHK Removable terminals blue LED green: Power supply LED yellow/red: Status output Ι/ Fault signal Function S 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 S. Switch S allows output to be switched between a signal output and an error message output. Switch S 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 NE. 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. Switch...

KCD-SR-Ex.LB Accessories Power feed module KFD-EB The power feed module is used to supply the devices with V DC via the Power Rail. The fuse-protected power feed module can supply up to 50 individual devices depending on the power consumption of the devices. Collective error messages received from the Power Rail activate a galvanically-isolated mechanical contact. Power Rail UPR-0 The Power Rail UPR-0 is a complete unit consisting of the electrical insert and an aluminium profile rail 5 mm x 5 mm. To make electrical contact, the devices are simply engaged. Profile Rail K-DUCT with Power Rail The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary. Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
