PLC控制柜的组成部分:

  1、空开:一个总的空气开关,这个是整个柜体的电源控制。相信每个柜子都必须要有的一个东西。

  2、PLC:这个要根据工程需要选择。打个比方如果工程小可以直接就是一个一体化的PLC但如果工程比较大可能就需要模块、卡件式的,同时还可能需要冗余(也就是两套交替使用)。

  3、24VDC的电源:一个24VDC的开关电源,大多数的PLC都是自带24VDC的电源,根据是否确实需要来定是否要这个开关电源。

  4、继电器:一般PLC是可以直接将指令发到控制回路里,但也可能先由继电器中转。打个比方,如果你PLC的输出口带电是24VDC的,但是你的控制回路里画的图需要PLC供的节点却是220VAC的,那么你就必须在PLC输出口加上一个继电器,即指令发出时继电器动作,但后让控制回路的节点接到继电器的常开或常闭点上。也是根据情况选择是否使用继电器。

  5、接线端子:这个肯定是每个柜子都必不可少的东西根据信号数量可以配置。如果只是一个单纯的PLC控制柜基本就是需要这些玩意,如果你的控制柜内还需要有其他的东西就看情况增加。比方说你有可能要对某些现场的仪表或者小控制箱供电,可能你就得要增加空开数量。或者你要PLC接至上位机,可能就需要增加交换机什么的。视情况而定。

  PLC控制柜可完成设备自动化和过程自动化控制,实现完美的网络功能,性能稳定、可扩展、抗干扰强等特点,是现代工业的核心和灵魂。可以根据用户需求量身设计PLC控制柜、变频柜等,满足用户要求,并可搭配人机界面触摸屏,达到轻松操作的目的。设备更可与dcs总线上位机modbus、profibus等通讯协议的数据传输;工控机、以太网等实现的控制和监控。



  PLC应用领域

  典型应用:水处理、恒压供水、空压机、风机水泵、中央空调、港口机械、机床、锅炉、造纸机械、食品机械等等。

  PLC控制柜概述

  PLC综合控制柜具有过载、短路、缺相保护等保护功能。它具有结构紧凑、工作稳定、功能齐全。可以根据实际控制规摸大小,进行组合,既可以实现单柜自动控制,也可以实现多柜通过工业以太网或工业现场总线网络组成集散(DSC)控制系统。PLC控制柜能适应各种大小规模的工业自动化控制场合。广泛应用在电力、冶金、化工、造纸、环保污水处理等行业中。

Components of PLC control cabinet:
1. Air switch: a general air switch, which is the power control of the whole cabinet. I believe every cabinet must have something.
2. PLC: this should be selected according to the needs of the project. For example, if the project is small, it can be an integrated PLC directly, but if the project is relatively large, it may need module and card type, and it may also need redundancy (that is, two sets are used alternately).
3. 24VDC power supply: a 24VDC switching power supply. Most PLCs have their own 24VDC power supply. Whether to use this switching power supply depends on whether it is really needed.
4. Relay: generally, PLC can directly send instructions to the control circuit, but it may also be transferred by the relay first. For example, if the output port of your PLC is charged with 24VDC, but the node drawn in your control circuit needs to be supplied by PLC is 220VAC, then you must add a relay to the PLC output port, that is, the relay acts when the command is issued, but then let the node of the control circuit connect to the normally open or normally closed point of the relay. Whether to use the relay is also selected according to the situation.
5. Wiring terminal: this must be essential for each cabinet. It can be configured according to the number of signals. If it's just a simple PLC control cabinet, you basically need these things. If you need other things in your control cabinet, it depends on the situation. For example, you may have to supply power to some field instruments or small control boxes, and you may have to increase the number of air switches. Or if you want to connect the PLC to the upper computer, you may need to add a switch or something. As the case may be.
PLC control cabinet can complete equipment automation and process automation control, realize perfect network function, and has the characteristics of stable performance, scalability and strong anti-interference. It is the core and soul of modern industry. PLC control cabinet and frequency conversion cabinet can be designed according to the needs of users to meet the requirements of users, and can be matched with man-machine interface touch screen to achieve the purpose of easy operation. The device can also transmit data with DCS bus host computer modbus, PROFIBUS and other communication protocols; Control and monitoring realized by industrial computer and Ethernet.
PLC application field
Typical applications: water treatment, constant pressure water supply, air compressor, fan water pump, central air conditioning, port machinery, machine tool, boiler, paper machinery, food machinery, etc.
Overview of PLC control cabinet
PLC integrated control cabinet has protection functions such as overload, short circuit and phase loss protection. It has the advantages of compact structure, stable operation and complete functions. It can be combined according to the actual size of the control gauge, which can not only realize the automatic control of a single cabinet, but also realize the distributed control system (DSC) composed of multiple cabinets through industrial Ethernet or industrial fieldbus network. PLC control cabinet can adapt to industrial automation control occasions of various sizes and scales. It is widely used in electric power, metallurgy, chemical industry, papermaking, environmental protection, sewage treatment and other industries.
