每个输入通道独立地处理所有输入数据，并将数据传递给主处理器，在主处理器中，在处理前对数据进行表决，以确保最高的完整性。每个PTI模块为每个信道提供完整的持续诊断，包括信道到信道计数比较。任何通道上的任何诊断失败都会激活模块的故障指示灯，进而激活机箱警报。故障指示灯指示通道故障，而不是模块故障。PTI模块保证在出现单个故障时正常运行，并且可以在出现某些类型的多个故障时继续运行。PTI模块可以使用或不使用热备用模块运行。如果您使用热备盘模块，它将重新教育活动模块中的所有计数器值。表49脉冲累加器输入模块型号电压点类型模块描述3515 24 VDC 32 TMR脉冲累加机输入130第2章Tricon v9–v10系统的系统组件规划和安装指南脉冲累加仪示意图此图是3515型的简化示意图，它是一个脉冲累加器输入模块。图54 3515现场电路典型点简化示意图（第1个，共32个）-智能I/O控制器-+A-+B-+C单个点现场测试光隔离AC/DC输入电路单个光隔离支路到支路隔离触发I/O总线计数器总线Xcvr计数器总线Xcvr计数器总线Xcvr阈值检测光隔离阈值检测光隔离器阈值检测光隔离器双端口RAM双端口RAM单端口RAMµProcµProc脉冲积算器输入模块131 Tricon v9–v10系统脉冲积算输入前面板规划和安装指南此图显示了3515型的前面板。故障激活紫色条纹132第2章Tricon v9-v10系统3515的系统组件规划和安装指导规格本表列出了3515型（脉冲累加器输入模块）的规格。表50 3515脉冲累加器输入规格特性规格颜色代码紫色输入点数量32，非公用输入频率范围0 Hz至1 KHz最小输入脉冲宽度300μs精度：有源模块+/-2计数精度：热备用模块，Tricon v9–v10系统16点隔离热电偶模块热更换系统组件规划和安装指南期间的最大错误计数该图是3708E型的简化示意图，该型号是一个隔离热电偶输入模块。图58 3708E简化的单个点场特性示意图智能I/O控制器（S）触发的I/O总线信号调节热电偶输入电路–每个支路多路复用器A CJ传感器总线Xcvr Amp ADC多路复用器B CJ传感器母线Xcvr放大器ADC多路复用电路C CJ传感器总线Xcvr-Amp ADCµProcµProc热电偶输入模块139Tricon v9–v10系统的规划和安装指南此图显示了3708E型的前面板。图59 3708E前面板深黄色条纹隔离热电偶3708E PASS FAULT ACTIVE CJ 140第2章Tricon v9–v10系统3708E规格系统组件规划和安装指南本表列出了3708E型号的规格，该型号为隔离TMR热电偶输入模块。小心•如果超过某个信道的共模电压范围，Triconex不能保证模块的正常运行和其他信道的准确性。
Each input channel independently processes all input data and passes the data to the Main Processors, where it is voted before processing to ensure the highest integrity. Each PTI module provides complete ongoing diagnostics on each channel, including channelto-channel count comparison. Failure of any diagnostic on any channel activates the module’s Fault indicator, which in turn activates the chassis alarm. The Fault indicator points to a channel fault, not a module failure. The PTI module is guaranteed to operate properly in the presence of a single fault, and may continue to operate with certain kinds of multiple faults. The PTI module can operate with or without a hot-spare module. If you use a hot-spare module, it re-educates all counter values from the active module.
