新型信号隔离器和安全栅的特点及扩展应用

Features and Extended Application of a Novel Signal Isolator and Safety Barrier

随着时代的发展,工业控制的智能化程度越来越高,系统的构成同过去相比发生了很大的变化,伴随着系统功能的增强,系统的组成也日益复杂和精密。为了适应系统的变化和发展,更好地发挥和保护系统,信号隔离器和安全栅被普遍地进行应用和推广。以前只在重要的场合采用隔离器和安全栅的设计和应用,现在已经作为设计的标准规范进行推广,因此,信号隔离器和安全栅也需要进一步发展适应当前的要求。

Following the development of the era, the intelligent level og process control becomes higher and higher. The changes of the system composition are much different from that in the past. The more enhancements are needed in system functions, the more complication and precision the compositions of system are. In order to meet the changes and development of the system, and the demands on protective function, applications of signal isolators and safety barriers become more popular. In the past, signal isolators and safety barriers were only used in critical applications, now these are stated in standard specifications. Thus for signal isolator and safety barrier themselves, further development will be necessary to meet such condition.
