Use of the existing rail terminal transmission coupling terminal WUK connection technology, and the installation of a circuit composed of electronic components to achieve a photovoltaic process.
　　Automatic control is the core of the control unit must be with the sensors and actuators reliably isolated to avoid interference, Sanmen Bay WUKG2 optical isolation terminal can properly fulfill this function, and to ensure that field signals and electronic control devices required low voltage matches the interface element between peripherals and control, signal and damper device also can be used for process control and for different voltages and power range.
　　Optical isolation terminal having a control terminal signal loss, high switching frequency, no mechanical contact bounce, no wear switching high voltage insulation, not afraid of vibration, regardless of location effect and long life, etc., so widely used in automatic control.
