OPI 1264
Series
Optically Coupled Isolators
BASEEFA & ATEX CERTIFIED
The OPI1264A/B/C/D are a family of
optically coupled isolators, each consisting of
a infrared light emitting diode, coupled to an
NPN silicon phototransistor sealed in an
injection moulded plastic housing. This series
is designed for applications requiring high
voltage isolation between input and output.
All electrical parameters are 100% tested by
manufacturing. Specifications are guaranteed
to a 0.65% AQL
•10KV electrical rating
•High current transfer ratio-100% min@
1m
•Designed and manufactured to
EN50020 1995 and EN50014 1998
