AC电源AC输入型PLC的输入接线AC电源AC输入型PLC的输入接线这种类型的PLC(基本单元和扩展单元)采用AC100~120V供电,该电压除了供给PLC的电源端子外,还要在外部提供给输入电路,在输入接线时将AC100120接在COM端子和开关之间,开关另一端接输入端子。扩展模块的输人接线扩展模块的输入接线由于扩展模块内部没有电源电路,它只能由外部为输人电路提供DC24V电压,在输入接线时将DC24V正极接扩展模块的24+端子,DC24V负极接开关,开关另一端接输人端子。
Flame retardant cable, is refers to under specified test conditions, specimen was, after removed test of ignition, flame spread only in a limited range, residual sheep and burning in the finite cable to self extinguishing in the course of time. The fundamental characteristic is that it may burn out and not run in the case of fire, but it can spread fire. Generally speaking, in case of electric wire fire, it can be put in the local scope, not to produce spread, keep other kinds of e, avoid causing greater loss. The meaning of the flame retardant cable: under specified test conditions, samples were, in is removed after the fire, the spread of flame on the sample only in a limited range and the characteristic of self extinguishing, which has the ability of or delay the outbreak or spread of flame.
使用条件1、额定电压U0/U:0.6/1KV.2、电缆导体长期允许最高温度为90度,短路时最高温度250度3、安装敷设环境温度不低于0度,固定敷设时环境温度不低于-10度.4、电缆允许最小弯曲半径不小于15D(D-电缆外径,mm)产品性能1、设计采用符合GB/T规定的第5类软绞合铜导体。
电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高,耐电压好,介电系数小和介质损耗温度和变频率的影响也小,不但能满足传输性能的要求,而且能确保电缆的使用寿命。为了减少回路间的相互串扰和外部干扰,电缆采用屏蔽结构。
