产品详情资料

PLC及各单元布置与CPU单元相邻的单元，是特殊单元和输入单元等干扰产生少的单元。外部电路的电磁接触器及电器类，其线圈及接点即干扰发生源，因此应与PLC分开配置。（大致在100mm以上）此外模块是PLC系统的主要部件，需经常进行调试维护，应安装在方便操作的位置。安装模块时自左向右排布，便于扩展。信号线较多，通常***80mm宽的线槽，机架上端与线槽的净距在30mm左右，机架下端与线槽的净距在80mm左右。PLC和变频器线的接法原则为防止plc和变频器之间的控制信号线受空间电磁场的干扰，可在这些控制信号线的外层接线，以提高系统的抗干扰能力。此种接线一定要注意，对的接地点只能选取一点。不管是在PLC一边，还是在变频器的一边。一般选在信号接收端，即变频器一边。这样，可提高系统的抗干扰能力。如果线在两端都接地，会使线上有电流流过，不但不能提高系统的抗干扰的能力，反而会加重外界对PLC的干扰。PLC柜型的选择适用于装PLC的柜型，通常***固定柜，且门板为整门的柜型，如KB柜、九折柜和十六折柜等，不宜选GGD柜、固定分割柜、抽屉柜。因为PLC柜内元件基本上为整板安装，如果采用了柜门分割的柜型，不便于安装和调试。对于GGD柜如果必须***时，需做一下非标设计，将仪表门、前门和下通风门合并成一个整门，且柜体框架上取消前后横梁，以便于安装和维护

英文产品详细信息

The PLC and its units are arranged adjacent to the CPU unit, which are units with less interference caused by special units and input units. The coils and contacts of electromagnetic contactors and electrical appliances in external circuits are the sources of interference, so they should be configured separately from the PLC. In addition, the module is the main component of the PLC system and requires frequent debugging and maintenance. It should be installed in a convenient location for operation. When installing modules, they are arranged from left to right for easy expansion. There are many signal lines, usually with a * * * 80mm wide slot. The clear distance between the upper end of the rack and the slot is about 30mm, and the clear distance between the lower end of the rack and the slot is about 80mm. The principle of connecting PLC and frequency converter cables is to prevent the control signal lines between PLC and frequency converter from being interfered by spatial electromagnetic fields. The outer layer of these control signal lines can be connected to improve the anti-interference ability of the system. Attention must be paid to this type of wiring, and only one point can be selected for the correct grounding point. Whether on the PLC side or on the frequency converter side. Generally, it is selected at the signal receiving end, which is on the side of the frequency converter. This can improve the system's anti-interference ability. If the line is grounded at both ends, there will be current flowing through the line, which not only cannot improve the system's anti-interference ability, but also exacerbates external interference with the PLC. The selection of PLC cabinet type is applicable to the cabinet type installed with PLC, usually fixed cabinet, and the door panel is a whole door cabinet type, such as KB cabinet, 9-fold cabinet, and 16-fold cabinet. It is not suitable to choose GGD cabinet, fixed partition cabinet, or drawer cabinet. Because the components inside the PLC cabinet are basically installed as a whole board, if a cabinet type with a split cabinet door is used, it is not convenient for installation and debugging. If it is necessary to * * * * for GGD cabinets, a non-standard design needs to be made by merging the instrument door, front door, and lower ventilation door into a single door, and removing the front and rear crossbeams from the cabinet frame for easy installation and maintenance
