- 【Material】：Adopting high quality transistor, superior performance, stable and reliable quality, the output signal optocoupler isolation, strong anti-interference ability.
- 【Widely used】: The output can control high-power devices, light bulbs, LED strips, DC motors, miniature pumps, solenoid valves and so on.
- 【Principle】: Through optoelectronic isolation and amplification of weak control (only a few milliamps of current), the final output of higher power control, direct drive motors, contactors, solenoid valves and so on.
- 【Advantages】: Its response time can be as low as milliseconds and there is no limit to the number of switches. It can directly replace traditional relays, reducing maintenance time and cost.
- 【Features】: Optical isolation is used between the input and output stages, and the two stages are completely independent, which effectively avoids the instability caused by mutual interference of the system, and effectively
