Terminal block is a kind of spare part product used to establish electrical connection, which is divided into the scope of terminal block in production. With the higher and higher level of automation, the regulations of industrial control system are more and more strict and accurate, and the use of terminal blocks is gradually increasing. With the development of the electronic industry, the application area and variety of terminal blocks are becoming larger and larger. In addition to PCB terminals, hardware terminals, screw terminals, torsion spring terminals, etc. are the most widely used.
Terminal block characteristics
Using the existing screw connection technology of the rail connector terminal frame, the power circuit composed of electronic components is modified, and the optical transmission of the lotus root optical isolation terminal is completed. The lotus root optical isolation terminal has the advantages of data signal consumption at the control end, high conversion frequency, no mechanical equipment contact chatter, no damage conversion, high working voltage of the insulation layer, no vibration, no vibration, no component damage, and long service life, Therefore, it has been widely used in the automatic control system industry.
The core content of the automatic control system is that the control module must be isolated from all sensors and electric actuators to prevent harm. The Sanmenwan WUKG2 optical isolation terminal can reasonably terminate this effect, and ensure that the on-site data signal is consistent with the low voltage required by the electronic device adjustment equipment. It can also be used for process operation of external machine equipment and manipulation, and the data signal and the socket components in the middle of the control machine equipment, And different operating voltage and output range shall be applied.
The photo thermal terminal has the advantages of control terminal data signal consumption, high conversion working frequency, no mechanical equipment contact point vibration, no damage conversion, high insulation layer working voltage, no fear of vibration, not affected by parts, long service life, etc., so it has been widely used in the automatic control system industry.
Terminal identification method
Machine equipment terminal blocks and special transmission line terminals can be identified by one or more of the following methods.
1. The specific or relative positions of machine equipment terminal blocks or special transmission line terminals shall be confirmed and identified by the identification system software of relevant products.
2. The color identification of machine equipment terminals and special transmission line terminals shall be confirmed and identified by the identification system software of relevant products.
3. Use the symbol pictures required in GB5465. If auxiliary marks are to be used, they shall be consistent with the figures in GB4728.
Application of terminal blocks
Colors, symbol pictures or English alphanumeric symbols shall be indicated at corresponding line ends or adjacent parts. When two or more identification methods are used and can be confused, the internal relationship of the two identification methods must be indicated in the relevant documents.
