PCB FUNCTIONAL SAFETY SIL SUMMARY AND RESULTS
Summary
This report details the results of the reliability analysis performed on the PCB Piezotronics ICP Sensor model
60X series. Design changes from this documentation package would need to be evaluated for the impact on
the reliability characteristics. These results are based on the following PCB Piezotronics documentation:
1. Electrical schematic 23402-NR
2. 603C01 MTTF Calculation
3. 602C1 I
