Characteristics of photoelectric relay:
1, low control power: it can work normally with small control current input, and the output adopts high-power thyristor device, which has power amplification effect.
2. Reliability: it is made of insulating and waterproof materials and has no moving parts.
3. Strong anti-interference ability: no contact action, no electromagnetic interference such as sparks, and input and output isolation.
3. Quick action: DC SSR- reaction time
4. Long service life:1012 ~1013 times (ordinary electromagnetic relay 105 ~ 106 times).
5. High surge current tolerance: 6 ~ 10 times the rated value.
6. Wide adaptability of power supply voltage: AC SSR-30 ~ 220 VAC.
7. High withstand voltage level: the withstand voltage of input/output medium is above 2.5kV.
