Page 7: Product Description
Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 Product Description Product Description Function General This isolated barrier is used for intrinsic safety applications. The device supplies power to solenoids, LEDs and audible alarms located in a hazardous area. The output signal has a resistive characteristic. As a result the output voltage and current are dependent on the load. - Page 8 Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 Product Description HiC2873Y1 This device is a 1-channel device. The device is bus powered. The device is controlled with a switch contact, transistor, or logic signal. At full load, 12 V at 40 mA (with 55 mA current limit) is available for the hazardous area application.

Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 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 11: Assumptions
Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 Planning Assumptions The following assumptions have been made during the FMEDA: • Failure rate based on the Siemens standard SN 29500. • The device will be used under average industrial ambient conditions comparable to the classification "stationary mounted" according to MIL-HDBK-217F. -
Page 12: Safety Function And Safe State
Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 Planning Safety Function and Safe State Safe State The safe state of the output is the de-energized state. The output current is less than 0.4 mA. Safety Function The output is de-energized if the input is in low state. The low state is reached when the input voltage is 5 V or below or the contact is open. -

Page 15: 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. -

Danger to life from missing safety function If the safety loop is put out of service, the safety function is no longer guaranteed. • Do not deactivate the device. • Do not bypass the safety function. - Page 18 Functional Safety HiD2872, HiC2873(Y1), HiD2876, HiC2877 Operation Equipment required: • Digital multimeter with an accuracy of 0.1 % Use for the proof test of the intrinsic safety side of the device a special digital multimeter for intrinsically safe circuits. If intrinsically safe circuits are operated with non-intrinsically safe circuits, they must no longer be used as intrinsically safe circuits.
