Series 8 I/O 通过一对 Combo 电缆接口连接到 S8 C300。两个冗余的组合电缆接口在 S8 C300 控制器和关联的 S8 I/O 模块之间提供 IO Link 连接,组合电缆接口连接器位于IOTA上。每根 Combo 电缆都可以配置为支持 8 系列 I/O。光纤选件扩展器模块支持将 I/O 链路扩展到 S8 C8 的 300 系列机柜之外，从而实现 8 系列 I/O 的远程应用。

8939-HN工业控制实现自动化与PLC的加入有非常大的关系，PLC在工业生产线中主要功能为：开环控制、模拟量闭环、数字量控制等，这在很多场景下可以取代传统的继电接触器控制系统，让工业控制系统实现自动化生产。此外，PLC除了控制外，还可以实现采集现场数据的功能，并且可以对数据进行统计和记录。

由于PLC 8939-HN大多数都使用了单片微型计算机，所以集成度非常高，这也增加了系统的可靠性。PLC的优势在于输入和输出功能模块兼具，可以针对现场不同的信号，8939-HN采用与之匹配的模板与对应的设备相连接并采取控制。除此之外，PLC还具备变成容易、组态灵活、安装方便、运行速度快。

当前在PLC领域中，企业基本上都属于欧美日三个地区。欧洲以西门子、施耐德为主，美国市场以罗克韦尔、通用为主，而日本市场则以欧姆龙、三菱和松下。而国产品牌在PLC 8939-HN方面近些年也发展迅速，和利时、信捷电气、南大傲拓、汇川技术、英威腾等自主品牌也在致力研发PLC，不过仍是以中小型PLC为主，大型的PLC系统仍被国际品牌占据，国内自主品牌仍有很大的进步空间。

脉冲变压器变压的信号要比不同电源变压器的频率高的多，一般为10K-100kHZ,而普通电源变压器为50HZ。这样脉冲变压器的效率就要比普通变压器高得多，体积亦可以小很多，体积可以缩小–这就是开关电源比线性电源(普通电源变压器的电源)的特点之一。把正弦波变成脉冲波输出的不是脉冲变压器而是变压器前端的控制电路。他通过把PWM信号把被波整流成直流的市电调制成高频的脉宽电压，通过脉冲变压器变压，然后通过滤波整流把变压后的脉宽电压变成直流。

The Series 8 I/O connects to the S8 C300 via a pair of Combo cable interfaces.

Two redundant combined cable interfaces provide an IO Link between the S8 C300 controller and the associated S8 I/O module.

The combined cable interface connector is located on IOTA.

Each Combo cable can be configured to support 8 series I/O. The Fiber Option extender module supports the expansion of I/O links beyond the 300 Series cabinets of the S8 C8, enabling remote applications of the 8 Series I/O.

8939-HN industrial control automation and the addition of PLC has a very large relationship, the main functions of PLC in the industrial production line are: open loop control, analog closed loop, digital control, etc., which in many scenarios can replace the traditional relay contactor control system, so that the industrial control system to achieve automated production. In addition, in addition to control, PLC can also achieve the function of collecting field data, and can be statistical and record the data.

Since most of the PLC 8939-HN uses a single chip microcomputer, the integration is very high, which also increases the reliability of the system. The advantage of PLC is that the input and output function modules are both, which can be used for different signals in the field, and the 8939-HN uses a matching template to connect with the corresponding equipment and take control. In addition, PLC also has easy to become, flexible configuration, convenient installation, fast running speed.

At present, in the field of PLC, enterprises basically belong to the three regions of Europe, America and Japan. The European market is dominated by Siemens and Schneider, the American market is dominated by Rockwell and General Motors, and the Japanese market is dominated by Omron, Mitsubishi and Panasonic. The domestic brand in PLC 8939-HN in recent years has also developed rapidly, Hollysys, XinjieElectric, Nanda Ao to, Huichuan technology, Yingweiteng and other independent brands are also committed to the development of PLC, but is still based on small and medium-sized PLC, large PLC system is still occupied by international brands, domestic independent brands still have a lot of room for progress.

The pulse transformer transformer signal is much higher than the frequency of different power transformers, generally 10K-100kHZ, while the ordinary power transformer is 50HZ. In this way, the efficiency of the pulse transformer is much higher than that of the ordinary transformer, the volume can also be much smaller, and the volume can be reduced - this is one of the characteristics of the switching power supply than the linear power supply (the power supply of the ordinary power transformer). It is not the pulse transformer that turns the sine wave into the pulse wave output, but the control circuit at the front of the transformer. He modulated the PWM signal to make high frequency pulse width voltage by the wave rectified into DC, changed the voltage through the pulse transformer, and then changed the pulse width voltage into DC through the filter rectification
