The existing rail-type terminal frame screw connection technology is used, and a circuit composed of electronic components is added to realize the transmission coupling of the photoelectric process.

The core of automatic control is that the control unit must be reliably isolated from each sensor and actuator to avoid interference. The Sanmen Bay WUKG optical isolation terminal can do this well and ensure the low requirements of the on-site signal and electronic control device. The voltages are matched and can also be used as interface components between process control peripherals and control, signal and regulator devices, and for different voltage and power ranges.

The optical isolation terminal has the advantages of low signal loss at the control end, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, no fear of vibration, no position influence and long life, so it is widely used in the field of automatic control.
