Optocouplers and alternative isolation technologies fnd widespread use in a variety of products for signal isolation and high voltage level shifting. These devices may also be used to provide safety related insulation. Considering these electrical concerns, it is necessary to understand the safety related characteristics of the optocoupler or alternative iso-lator.

Safety Considerations When Using Optocouplers
and Alternative Isolators for Providing
Protection Against Electrical Hazards

White Paper



Introduction
Optocouplers and alternative isolation technologies find For aerospace a factor of safety of 1.25 is typically used. In
widespread use in a variety of products for signal isolation these applications, weight penalties are extreme and the
and high voltage level shifting. These devices may also be costs of higher quality control and frequent servicing checks
used to provide safety related insulation. Considering these are more tolerable. So on this basis, a lower safety factor is
electrical concerns, it is necessary to understand the safety justifiable. For safe electrical insulation applications, often
related chara
