AMC1304 datasheet Page-7 is described about safety limiting value.
Although care about no exceed safety limit, I think that input circuit have difficult case for safety condition.
Please let me know about two points below;
①Is there reference circuit for prevent to exceed safety limit? (Especially I want to see input side)
②Is there any test data in the case of exceed safety limit?
For example, whether isolation barrier is break (damage) or not.
