Data Sheet
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 INSULATION CHARACTERISTICS
These isolators are suitable for reinforced electrical isolation within the safety limit data only. Maintenance of the safety data is ensured by
protective circuits. The asterisk (*) marked on packages denotes DIN V VDE V 0884-10 approval.
