详细介绍


3481  模拟输出模块

数字输出模块每个TMR数字输出模块都有三组隔离的电子设备,称为通道,它们独立接收来自与每个通道相关的MP的数据。这些通道使用获得的四路表决器电路对施加于负载的单个输出信号进行表决。这种表决器电路基于并联串联路径,如果三个开关中的两个(通道A和B,或通道B和C,或通道A和C)命令它们闭合,这些路径就会传递功率。四重表决电路在所有关键信号路径上都有多重冗余,保证了安全性和大的可用性。对于每个点,DO模块定期执行输出表决器诊断(OVD)程序。为了允许在各种多故障情况下不受限制的安全运行,OVD检测并报警这些类型的故障:点一-所有卡在接通和卡在断开位置的故障在不到500毫秒内被检测到。开关一检测到所有 卡在on位置或卡在off位置的开关或其相关驱动电路。DO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。DO模块保证在出现单一故障时正常运行, 并且在出现某些多重故障时仍可继续正常运行。模块是否支持热备盘模块。每个DO模块都用机械键固定,以防止在已配置的基板中安装不当。

Each TMR digital output module has three sets of isolated electronic devices called channels, which independently receive data from the MP associated with each channel. These channels use patented four channel voting circuits to vote on a single output signal applied to the load. This voter circuit is based on a parallel series path, and if two of the three switches (channels A and B, or channels B and C, or channels A and C) command them to close, these paths will transmit power. The quadruple voting circuit has multiple redundancy on all critical signal paths, ensuring safety and maximum availability. For each point, the DO module periodically executes the Output Voter Diagnostic (OVD) program. In order to allow unrestricted safe operation in various multi fault situations, OVD detects and alarms these types of faults: point one - all faults stuck on and off are detected in less than 500 milliseconds. Switch 1 detects all switches or their related drive circuits that are stuck in the on or off position. The DO module includes complete and continuous diagnostics for each channel. 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. The DO module ensures normal operation in the event of a single fault and can continue to operate normally in the event of certain multiple faults. Does the module support hot spare modules. Each DO module is fixed with mechanical keys to prevent improper installation in the configured substrate.
