Utilizing universal terminal blocks and electronic device to realize photo-coupling, to isolate the input and output signals.
The isolation technology between the return circuit and on-the -spot circuit are more and more inportant with the improvement of the automatics.
As the auto-control core, the control unit must be reliably isolated with every sensor and performer, to avoid disturb with each other. The photo-coupling technology is used more and more in reality for following advantages:
1.Signal consumption is small, the frequency of the switch is high.
2.There's no mechanicl moement ,no vibration. The insulating voltage is high.
3.Not afraid of vibration.
4.Volume is not limited by the position , it is convenient to wire
