Features 1、Isolate and amplify the weak control signal (only a few milliamps of current) by photoelectricity, and finally output a higher power control signal to directly drive the motor, contactor, solenoid valve, etc. 2、The response time is as low as milliseconds and there is no limit on the number of switches. It can directly replace traditional relays, reducing maintenance time and costs. 3、Photoelectric isolation is used between the input stage and the output stage, and the two stages are completely independent, which effectively avoids the instability caused by mutual interference of the system and effectively protects the output node of the PLC. 4、Made of high-quality electronic components, stable and reliable performance. 5、Hole punching and PCB module mounting are more convenient.
