Other Parts Discussed in Thread: ISO7741, ISO7841
ISO7241C datasheet states:
1. "This coupler is suitable for basic electrical insulation only within the maximum operating ratings."
Viorm is 560 Vpk.
If permanent votage across I/O isolation barrier is much less than 560 Vpk in application, e.g. 50 Vpk, can ISO7241C be declared as reinforced isolation component?
2. "Compliance with the safety ratings shall be ensured by means of suitable protective circuits."
Is there a reference design of such protctive circuit, e.g. to achieve safety limiting values?
