Data Sheet
DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS
This isolator is suitable for reinforced isolation only within the safety limit data. Maintenance of the safety data is ensured by protective
circuits. The asterisk (*) marking on the package denotes DIN V VDE V 0884-10 approval for a 560 V peak working voltage.
