TRICONEX DI3301冗余模块,DI3301卡件
64点数字输入
模块
每个64点数字输入(DI)
模块有三个隔离通道
独立处理所有数据TRICONEX DI3301
输入到模块。微处理器
在每个通道上扫描每个输入点,
编译数据并将其传输到
按需提供主处理器。然后
输入数据在处理之前在主进程或SOR上进行表决,以确保
最高诚信。
所有数字输入模块支持
为每个
频道任何通道上的故障都会激活故障指示灯,从而
激活底盘警报。TMR
模块保证在出现单一故障时正常运行,并且
可与某些类型的TRICONEX DI3301
多个故障。
所有数字输入模块都支持热备用模块,并且需要单独的
外部终端面板(ETP),带有
Tricon背板的电缆接口。
每个模块通过机械键连接到
防止在
底盘。
64-Point Digital Input
Modules
Each 64-point Digital Input (DI)
module has three isolated channels
which independently process all data
input to the module. A microprocessor
on each channel scans each input point,
compiles data and transmits it to the
Main Processors on demand. Then
input data is voted at the Main Proces
sors just prior to processing to ensure
the highest integrity.
All Digital Input Modules sustain
complete, ongoing diagnostics for each
channel. A failure on any channel acti
vates the Fault indicator which in turn
activates the chassis alarm. A TMR
module is guaranteed to operate prop
erly in the presence of a single fault and
may operate properly with certain kinds
of multiple faults.
All Digital Input Modules support hot
spare modules and require a separate
external termination panel (ETP) with a
cable interface to the Tricon backplane.
Each module is mechanically keyed to
prevent improper installation in a
chassis.
