FX0N-65EC扩展电缆是不是必须配一个FX2N-CNV-BC转换接头才能连接使用啊?FX0N-65EC当连接FX2N-32ER/ET、FX2N-48ER/ET时,不需要加FX2N-CNV-BCFX2N系列PLC型号后缀ES/UL跟-001有什么区别?1.后缀为ES/UL为欧版型号,-001为中国大陆版。
-ES/UL系列输入方式可通过S/S端子,而选择源型、漏型输入方式。
而-001系列输入方式固定为漏型输入。

Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the buried depth of 1-35kv cable is not less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature is not lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and accidents such as burning sheath. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.

什么是plc?PLC又叫可编程控制器,是一种数字运算操作电子系统,专为在工业环境下应用而设计,它采用了可编程的存储器,用来在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令。
并通过数字的、模拟的输入和输出,控制各种类型的机械或生产过程,可编程控制器及其有关的外围设备,都应按易于与工业控制系统形成一个整体、易于扩充其功能的原则设计。
PLC控制与继电器控制的区别组成器件不同触点数量不同控制方法不同工作方式不同PLC控制、继电器和单片机控制的比较PC控制与继电器控制相比,具有改变程序就能变换控制功能的优点,但在简单控制时成本较高,利用单片机也可以实现控制。
