Isolated Grounds?
Posted: Fri 12. Jul 2019, 15:25
This may seem like a silly question, but the documentation for this device doesn't explicitly state it and isn't very thorough. Are the two Signal Grounds on the primary and secondary side of the Optoadapter isolated from each other? The datasheet labels them both as GND instead of as GND-Primary and GND-Secondary which would be a clear way to indicate they are separate signals. I'm assuming they are, otherwise this device wouldn't do very much, but I'm frustrated by the lack of clear documentation and I've found making assumptions about electronic systems is never a good idea.
