Safety Manual SIL KFD0-RSH-1(-Y2), KFD2-SL-4 Introduction KFD2-SL-4 The devices are 4-channel signal conditioners with outputs that switch up to 600 mA to high-power solenoids. The devices are also used as power amplifier up to a switching frequency of 1 kHz. -
Page 6: Planning
Safety Manual SIL KFD0-RSH-1(-Y2), KFD2-SL-4 Planning Planning System Structure 2.1.1 Low Demand Mode of Operation If there are two 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 7: Assumptions
Safety Manual SIL KFD0-RSH-1(-Y2), KFD2-SL-4 Planning Assumptions The following assumptions have been made during the FMEDA analysis: The device shall claim less than 10 % of the total failure budget for a SIL2 safety loop. For a SIL2 application operating in Low Demand Mode the total PFD value ... -

Safety Manual SIL KFD0-RSH-1(-Y2), KFD2-SL-4 Safety Recommendation Safety Recommendation Interfaces The device has the following interfaces. For corresponding terminals see data sheet. Safety relevant interfaces: KFD0-RSH-1(-Y2): input, output KFD2-SL-4: inputs, outputs, common disable input Configuration KFD0-RSH-1(-Y2) A configuration of the device is not necessary and not possible. -
Page 13: Installation And Commissioning
Safety Manual SIL KFD0-RSH-1(-Y2), KFD2-SL-4 Safety Recommendation Our experience has shown that the useful life time of a Pepperl+Fuchs product can be higher if there are no components with reduced life time in the safety path (like electrolytic capacitors, relays, flash memory, opto coupler) which can produce dangerous undetected failures and if the ambient temperature is significantly below 60 °C. -
