產(chǎn)品詳情資料

PLC及各單元布置與CPU單元相鄰的單元，是特殊單元和輸入單元等干擾產(chǎn)生少的單元。外部電路的電磁接觸器及電器類，其線圈及接點(diǎn)即干擾發(fā)生源，因此應(yīng)與PLC分開配置。（大致在100mm以上）此外模塊是PLC系統(tǒng)的主要部件，需經(jīng)常進(jìn)行調(diào)試維護(hù)，應(yīng)安裝在方便操作的位置。安裝模塊時自左向右排布，便于擴(kuò)展。信號線較多，通常***80mm寬的線槽，機(jī)架上端與線槽的凈距在30mm左右，機(jī)架下端與線槽的凈距在80mm左右。PLC和變頻器線的接法原則為防止plc和變頻器之間的控制信號線受空間電磁場的干擾，可在這些控制信號線的外層接線，以提高系統(tǒng)的抗干擾能力。此種接線一定要注意，對的接地點(diǎn)只能選取一點(diǎn)。不管是在PLC一邊，還是在變頻器的一邊。一般選在信號接收端，即變頻器一邊。這樣，可提高系統(tǒng)的抗干擾能力。如果線在兩端都接地，會使線上有電流流過，不但不能提高系統(tǒng)的抗干擾的能力，反而會加重外界對PLC的干擾。PLC柜型的選擇適用于裝PLC的柜型，通常***固定柜，且門板為整門的柜型，如KB柜、九折柜和十六折柜等，不宜選GGD柜、固定分割柜、抽屜柜。因?yàn)镻LC柜內(nèi)元件基本上為整板安裝，如果采用了柜門分割的柜型，不便于安裝和調(diào)試。對于GGD柜如果必須***時，需做一下非標(biāo)設(shè)計(jì)，將儀表門、前門和下通風(fēng)門合并成一個整門，且柜體框架上取消前后橫梁，以便于安裝和維護(hù)

英文產(chǎn)品詳細(xì)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
