Page 7: Product Description
Functional Safety KCD2-SON-Ex*(.R*)(.SP) Product Description Product Description Function General This devices are used for intrinsic safety applications. The devices transfer digital signals (NAMUR sensors or dry contacts) from the hazardous area to the non-hazardous area. The devices offer line fault transparency on the signal lines. A fault is signalized by LEDs and a separate collective error message output. -

Page 9: Planning
Functional Safety KCD2-SON-Ex*(.R*)(.SP) Planning Planning System Structure 3.1.1 Low Demand Mode of Operation If there are two control loops, one for the standard operation and another one for the functional safety, then usually the demand rate for the safety loop is assumed to be less than once per year. -
Page 10: Assumptions
Functional Safety KCD2-SON-Ex*(.R*)(.SP) Planning Assumptions The following assumptions have been made during the FMEDA: • The device shall claim less than 10 % of the total failure budget for a SIL 2 safety loop. • For a SIL 2 application operating in low demand mode the total PFD value of the SIF (Safety Instrumented Function) should be smaller than 10 , hence the maximum... -
Page 11: Safety Function And Safe State
Functional Safety KCD2-SON-Ex*(.R*)(.SP) Planning Safety Function and Safe State Safe State The safe state of output I and output II is the high impedance state or the fault state. The fault state is the open circuit. The high impedance state is defined as 0-signal in respective datasheet. - Page 12 Functional Safety KCD2-SON-Ex*(.R*)(.SP) Planning LB/SC Diagnosis The input loops of all versions are supervised, if the line fault detection is active (mandatory, see datasheet). The related safety function is defined as the outputs are in fault state (safe state), if there is a line fault detected. Note! The collective error message output is not safety-relevant.

Page 14: Useful Lifetime
As noted in DIN EN 61508-2:2011 note N3, appropriate measures taken by the manufacturer and plant operator can extend the useful lifetime. Our experience has shown that the useful lifetime of a Pepperl+Fuchs product can be higher if the ambient conditions support a long life time, for example if the ambient temperature is significantly below 60 °C. -
