Safety and Insulation Ratings

As per DIN EN/IEC 60747-5-5, this optocoupler is suitable for “safe electrical insulation” only within the safety limit

data. Compliance with the safety ratings shall be ensured by means of protective circuits.

Note:

1. Safety limit values – maximum values allowed in the event of a failure.
