These terminals utilize established rail-mounted, screw-clamp connection technology and incorporate an integrated electronic circuit to achieve signal transmission and coupling via optoelectronic means.
A core requirement of automatic control systems is the reliable isolation of the control unit from sensors and actuators to prevent interference. Sanmenwan WUKG2 opto-isolated terminal blocks effectively perform this function, ensuring compatibility between field signals and the low-voltage requirements of electronic control units. They serve as interface components between process control peripherals and control, signal, or regulating devices, and are suitable for a wide range of voltage and power specifications. Opto-isolated terminals offer numerous advantages-such as low signal loss at the control input, high switching frequency, absence of mechanical contact bounce, wear-free switching, high isolation voltage, vibration resistance, immunity to mounting orientation, and long service life-making them widely used in the field of automatic control.
