1. Excellent electrical isolation performance: optocoupler relays are isolated by optical signals, and can achieve electrical isolation of up to several thousand volts, which greatly improves the safety and reliability of the system.
2. Fast response speed: Due to the absence of mechanical contacts, the response speed of optocoupler relays is faster than that of traditional electromagnetic relays, and the signal transmission can be completed within microseconds.
3. No mechanical wear and tear: Optocoupler relays have no mechanical moving parts, avoiding the life limitation caused by mechanical wear and tear, and therefore have a longer service life.
4. Strong anti-interference ability: Optocoupler relays are not affected by electromagnetic interference, suitable for a variety of high-frequency and strong interference environment.
5. Low power consumption: Since only a small current is needed to drive the LED, the power consumption of optocoupler relays is relatively low, which helps to save energy.
