3301  DI输入模块

数字输入模块每个TMR数字输入模块都有三组隔离的电子设备,称为通道，它们独立处理模块的现场数据。每个通道将处理后的数据放在一个数组

中，并根据请求将该数组传输到与该通道相关联的MP。MPs在将数据传递给应用程序之前对其进行表决。DI模块包括每个通道的完整、持续的诊

断。如果诊断程序在任何通道上检测到故障，故障指示灯会亮起并激活系统警报。故障指示器识别通道故障，而不是整个模块故障。DI模块持续验

证系统检测向相反状态转变的能力。DI模块保证在出现单个故障时正常运行，并且在出现多个故障时也能继续正常运行。DI模块支 持热备用模块。

每个DI模块都是机械锁定的，以防止在已配置的基板中安装不当。

Each TMR digital input module has three sets of isolated electronic devices called channels, which independently process the module's field data. Each channel places the processed data in an array

And transfer the array to the MP associated with the channel according to the request. MPs vote on data before passing it to the application. The DI module includes complete and continuous diagnosis for each channel

Break. If the diagnostic program detects a fault on any channel, the fault indicator light will light up and activate the system alarm. The fault indicator identifies a channel fault, rather than an entire module fault. DI module continuous verification

The ability of the system to detect transitions to opposite states. The DI module ensures normal operation in the event of a single fault and can continue to operate normally in the event of multiple faults. The DI module supports hot standby modules.

Each DI module is mechanically locked to prevent improper installation in the configured substrate
