Hi, i´m sorry about my english, but i dont know to write very well.
I need configurated a Data signal Adquisition and i choose the cDAQ modules:
NI 9229 to proximity probe
NI 9233 to accelerometes
NI 9237 to strain gages
I have many questions about the boards and the global system.
1. What is the difference between overvoltage protection and Isolation??
2. How i can synchronize the three tarjets??? Some of then need i some particular position???
3. How i can synchronize the input of this boards??? Th three NI 99xx have differents input delay
Respect Ni 9229
4 This targets have screw terminals input. How i can connect a SMB input?
5 What is NI 9971 and NI 9976?? so that they serve?
6 to Specifications... is correct say the maximun transient voltage is 250 V?
Respect NI 9233
7 Why does not have values to Isolation???
Respect NI 9237
8 Can i connect different types of bridge in the channels??? For example. Ch0------->Full bridge; Ch1, Ch2----> Half bridge and simultaneous adcquired?
9 Why half and full bridge are "internal"? Why quarter bridge are external? ¿can i measured quarter bridge?
10 What are te NI 9942-9944-9945 and 9949??? so that they serve??
thanks so much to any help.
