According to the latest research from the Discrete Machine-Safety Components Annual Service,revenues from safety I/O are projected to grow faster than those from standard I/O.Digital modules in safety I/O remain the most popular globally;and most likely to remain so,as analogue costs more and can be seen as unnecessary.
根据《离散机器安全组件年度报告》的最新研究，安全I/O的收入预计将比标准I/O的收入增长更快。安全I/O中的数字模块仍然是全球最受欢迎的，并极有可能保持这样，因为模拟模块成本更高，而且非必要。
