NI SHC68-68-EPM 8通道脉冲量输入模块 与对应端子模块配套使用

SHC68-68-EPM是NI（National Instruments，国家仪器）公司生产的SM系列硬件产品中的8通道脉冲量输入模块。它通过64针欧式连接器与机笼底板连接，与对应端子模块配套使用，从现场输入8路脉冲信号。

该模块的测频和计数功能可根据用户的不同需求进行组态，每一通道既可设置为测频功能，也可设置为计数功能，并且允许同一块SHC68-68-EPM既有测频通道又有计数通道。

SHC68-68-EPM is an 8-channel pulse input module in the SM series hardware products produced by NI (National Instruments). It is connected to the cage base plate through a 64 pin European connector and used in conjunction with the corresponding terminal module to input 8-way pulse signals from the field.
The frequency measurement and counting functions of this module can be configured according to different user needs. Each channel can be set as a frequency measurement function or a counting function, and allows the same SHC68-68-EPM to have both frequency measurement and counting channels.
