Characteristics and drawing requirements of wiring terminals
In order to realize the transmission coupling of photoelectric process, the existing track needs to be used Terminal block Frame screw connection technology to install circuits composed of electronic components.
The core of automatic control is that the control unit must be reliably isolated from each sensor and actuator to avoid interference. Sanmenwan wukg2 optical isolation terminal can well complete this function, ensure that the field signal is consistent with the low voltage required by the electronic control device, and can also be used as the peripheral equipment of process control and the interface component between control, signal and regulation devices, Suitable for different voltage and power ranges.
Terminal block characteristic:
It has the advantages of low signal loss at the control end, high switching frequency, no mechanical contact vibration, no wear switching, high insulation voltage, no vibration, no position influence, long service life, etc. Therefore, it is widely used in the field of automatic control.
Terminal block Drawing requirements:
1） Terminal block The drawing of wiring diagram and wiring table shall comply with the provisions of drawing function table diagram of control system in gb6988.6-1993
2) All Terminal block And its leads shall be marked with text symbols and wiring numbers consistent with the electrical schematic diagram. The item number, terminal number and conductor number in the schematic diagram shall comply with item number in Electrical Technology (gb5094-1985) and electrical equipment (gb4026-1992)Terminal block And identification and application of specific conductor terminals, general rules of alphanumeric system and gb4884-1985 marking of insulated conductors, etc
3) Different from the electrical schematic diagram, it must be Terminal block Each part (contact, coil, etc.) connecting the same wiring terminal in the wiring diagram
4） Terminal block Wiring diagrams are drawn with thin lines. There are two kinds of wiring modes: front board wiring and rear board wiring. Generally, front board wiring is adopted. For simple electrical control components, the number of wiring terminals is small and the wiring relationship is not complex. The components with complex wiring between components can be directly drawn. When the number of wiring terminals is large and the wiring is complex, the wiring slot is generally used
5） Terminal block The wiring diagram shall indicate various wiring models, specifications, cross-sectional area and color requirements for wiring
6) When the parts are connected with the external circuit, the incoming and outgoing wires of large section conductors shall be connected by connectors, and others shall be connected by connectors Terminal block Row connection.
