plc和dcs在工业自动化控制中占有举足轻重的地位,而工业自动化控制是国家工业发展战略的核心。PLC以及DCS在工业控制的各个环节中不断的升级、完善,已经成为现代工业生产制造中不可或缺的工具。DCS和PLC的定义DCS控制系统,在国内自控行业又称之为集散控制系统。即所谓的分布式控制系统,是相对于集中控制系统而言的一种新型计算机控制系统,它是在集中控制系统的基础上发展、演变而来的。DCS作为一个集过程控制和过程监控为一体的计算机综合系统,在通信网络的不断带动下,DCS系统已经成为了一个综合计算机,通信、显示和控制等4C技术的完整体系。

In order to maintain compatibility, EIA/TIA 568B is commonly used to make mineral net wire. A wiring is applied to the whole network wiring, but the network connection with rj-45 socket at both ends is feasible in the network whether it is 568A or 568B.

Summary: fire-resistant cable refers to the cable which can keep safe running for a certain time under the condition of flame burning. China's national standard GB12666.6 IEC331 (e) will fire test points A, B two levels, A grade flame temperature of 950 ~ 1000 ℃, the duration for fire, 90 min, class B flame temperature of 750 ~ 800 ℃, for fire duration 90 min, during the whole test, the sample should be under the rated voltage value of the product. Fire-resistant cable is widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit. Purpose: fireproof cables are widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit.

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user re

  RVV电线全称铜芯聚氯乙烯绝缘聚氯乙烯护套软电线,又称轻型聚氯乙烯护套软线,俗称软护套线,是护套线的一种。主要用于中、轻型移动电器、仪表仪器、家用电器、动力照明等柔性使用场所,可传输控制信号,也可传输动力信号,也适合敷设在桥架和软管中。

两路比较器的输出端与R-S触发器的置位和复位相接,从而决定芯片3脚输出端的电平状态。当芯片2脚(/TR端)输入信号电压低于1/3Vcc时,N1输出端为“0”,R-S触发器被置位,芯片3脚变高电平,(在复位信号未输入之前)并保持;当芯片6脚输入电压高于2/3Vcc时,N2输出端为“1”,R-S触发器被复位(在置位信号未输入之前)并保持。芯片4为优先复位端(低电平有效),不用时可接Vcc。显然,作为开关电路应用时,只要控制芯片2脚电压低于1/3Vcc,电路处于“开”态(3脚为“1”);控制芯片6脚高于2/3Vcc,电路即处于“关”态(3脚为“0”),即为开关(双稳态)电路。
