About the characteristics of the terminal block:
Utilizing the existing track-type terminal WUK connection technology, and adding a circuit composed of electronic components, the transmission coupling of the photoelectric process is realized.
The core of automatic control is to isolate the control unit from the sensors and actuators to avoid interference. Sanmenwan WUKG2 optical isolation terminals can perform this function well, and the field signal matches the low voltage required by the electronic control device. , It can also be used as the interface component between process control peripheral equipment and control, signal and regulator device, and is suitable 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 positional influence, and long life. Therefore, it is widely used in automatic control.

Identification method of terminal:

One or more of the following methods can be used to identify equipment terminals and specific wire ends.

1. Use the marking system of related products to determine and identify the actual or relative position of the equipment terminal or specific wire end.

2. Use the marking system of related products to determine and identify the color markings of the equipment wiring terminals and specific wire ends.

3. Use the graphic symbols specified in GB5465. If auxiliary symbols are needed, they should be consistent with the graphics in GB4728.

4. Use the alphanumeric symbols specified in Chapter 5 of this standard.
