Page 7: Product Description
Functional Safety HiD2024 Product Description Product Description Function This isolated barrier is used for intrinsic safety applications. Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data. The outputs are fully isolated from the inputs, the power supply, and each other. -
Page 8: Planning
Functional Safety HiD2024 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 9: Assumptions
Functional Safety HiD2024 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... -
