The difference between relays with optocouplers and those without optocouplers (i.e. mechanical):
Relay (with optocoupler): contactless, high operating frequency (fast speed), small load capacity (Shu'an level), long service life
Relay (without optocoupler or mechanical): with physical contacts (sparks may be generated when connected and segmented), low operating frequency, strong load capacity, and relatively short mechanical life.
