WebMay 6, 2024 · aarg July 11, 2024, 11:46pm 2 Optocouplers are cheaper than a relay, longer lasting than a relay, use a lot less power than a relay, and handle less power than a relay. So for input it makes no sense to use a relay because the inputs don't use significant power. For output it might, since the relay can switch high power devices.
