When to Use Digital Isolators vs. Optocouplers
Designing isolation into your system is critical to protect both systems and users from potentially hazardous voltages. Since industrial equipment must operate safely and reliably in the harshest environments—where strong electromagnetic fields, surges, fast transients, and high noise floors are the norm—designing reliable isolation circuits that deliver error-free operation over long equipment lifetimes can be challenging. This white paper discusses isolation circuits designed to withstand the rigors of industrial environments, comparing optocouplers to RF-based digital isolators to help you select the best technology for your application.
