產品詳情資料：

係統設的工作量小，維護方便，容易改造

　　(1) 設計與維護

　　PLC用存儲邏輯代替接線邏輯，大大減少了控制設備外部的接線，使控制係統設計及建造的周期大為縮短，同時日常維護也變得容易起來，更重要的是使同yi設備經過改變程序而改變生產過程成為可能。特別適合多品種、小批量的生產場合。

　　(2) 安裝與布線

　　動力線、控制線以及PLC的電源線。

　　電源線是用作電氣組件或設備與電源的連接線，通常來說指電線與其yi端連接的插頭或尾插的集合體，是電器產品的基本零部件之yi。電源線分為電線和插頭兩部分。

和I／O線應分別配線，隔離變壓器與PLC和I／O之間應採用雙絞線連接。將PLC的I／O線和大功率線分開走線，如必xu在同yi線槽內，分開捆扎交流線、直流線，若條件允許，分槽走線zui好，這不僅能使其有盡可能大的空間距離，並能將幹擾降到zui低限度。

　　PLC應遠離強幹擾源如電焊機、大功率硅整流裝置和大型動力設備，不能與gao壓電器安裝在同yi個開關櫃內。在櫃內PLC應遠離動力線(二者之間距離應大於200 mm)。與PLC裝在同yi個櫃子內的電感性負載，如功率較大的繼電器、接觸器的線圈，應並聯RC消弧電路。

　　PLC的輸入與輸出zui好採用分開走線，開關量與模擬量也要分開敷設。模擬量信號的傳送應採用屏蔽線，屏蔽層應yi端或兩端接地，接地電阻

　　電阻，物質對電流的阻礙作用就叫該物質的電阻。電阻小的物質稱為電導體，簡稱導體。電阻大的物質稱為電絕緣體，簡稱絕緣體。應小於屏蔽層電阻的1／10。

　　交流輸出線和直流輸出線不要用同yi根電纜，輸出線應盡量遠離gao壓線和動力線，避免並行。

　　電纜是yi種用以傳輸電能信息和實現電磁能轉換的線材產品。既有導體和絕緣層，有時還加有防止水份侵入的嚴密內護層，或還加機械強度大的外護層，結構較為復雜，截面積較大的產品叫做電纜。

The workload of system design is small, easy to maintain, and easy to modify

(1) Design and Maintenance

PLC replaces wiring logic with storage logic, greatly reducing the external wiring of control equipment, greatly shortening the design and construction cycle of the control system, making daily maintenance easier, and more importantly, making it possible for the same equipment to change the production process through program changes. Especially suitable for multi variety and small batch production occasions.

(2) Installation and wiring

Power lines, control lines, and PLC power lines.

A power cord is used as a connecting wire between electrical components or equipment and a power source. Generally speaking, it refers to the collection of plugs or tail plugs that connect the wire to its end, and is one of the basic components of electrical products. The power cord is divided into two parts: wires and plugs.

The and I/O lines should be wired separately, and the isolation transformer should be connected to the PLC and I/O using twisted pair cables. Separate the I/O lines and high-power lines of the PLC from each other. If necessary, bundle the AC and DC lines separately in the same trunking. If conditions permit, divide the trunking and route them well. This not only allows for maximum space distance, but also reduces interference to a minimum.

PLC should be kept away from strong interference sources such as welding machines, high-power silicon rectifier devices, and large power equipment, and should not be installed in the same switchgear as any other piezoelectric devices. The PLC inside the cabinet should be kept away from the power line (the distance between the two should be greater than 200 mm). Inductive loads installed in the same cabinet as PLCs, such as high-power relays and contactor coils, should be connected in parallel with RC arc suppression circuits.

The input and output of PLC should be wired separately, and the switching and analog quantities should also be laid separately. The transmission of analog signals should use shielded wires, and the shielding layer should be grounded at one or both ends, with a grounding resistance

The resistance of a substance to an electric current is called its resistance. Substances with low resistance are called electrical conductors, abbreviated as conductors. Substances with high resistance are called electrical insulators, abbreviated as insulators. It should be less than 1/10 of the shielding layer resistance.

Do not use the same cable as the AC output line and DC output line. The output line should be as far away from the voltage line and power line as possible to avoid parallelism.

Cable is a wire product used to transmit electrical energy information and achieve electromagnetic energy conversion. A product with a complex structure and a large cross-sectional area is called a cable, which includes both a conductor and insulation layer, and sometimes a tight inner protective layer to prevent water intrusion, or an outer protective layer with high mechanical strength.
