Hello! I have 10-Analog continuous available signal for machine condition monitoring. 3-voltage (diff.), 3-current (com.ref.),2-vibration (com.ref.),and 2-temp (com.ref.), the voltage range of each signal is 0 to +5V. Kindly suggest me wiring configuration with SCB-68. for these input, which are the Not-Connect terminals for this data acquisition configuration

Hello,
Greetings ! Thank you for choosing National Instruments !
Which DAQ card are you using? The terminals on the SCB-68 are going to depend on which DAQ-card you are using. These terminals should be the ones that correspond to the respective channels on your DAQ device that you are using for this continuous analog input operation.
So for example, if you are using an E-series DAQ board, you can set channel 0 for differential input with say channel 8, and set channel 1 for Referenced Single Ended input, then the wires should go to the terminals 68 (AI 0), 34 (AI 😎 and 33(AI 1) on SCB-68.
Please let me know if this answers your question.

Thankyou, for your answer. I am using DAQCard AI-16E-4 (E-series) with SCB-68. now please continue your answer in detail for all input connections and NC pins. What is 'Dither'? may I improve resolution of my vibration signal. How is that?

Hello,
Greetings! The pin-out diagrams for all the E-series DAQ devices are available on NI website as well as under MAX.
On web:
http://digital.ni.com/manuals.nsf/websearch/AB6BECBCD482365286256EC900675A0F?OpenDocument&node=1051_US
The pin-out diagram for your 68 pin device can be found under I/O Connector in this manual.
Under MAX:
Go to Help>>Help Topics>>Traditional NI-DAQ. The pin-outs are under 'Traditional NI-DAQ Device Terminals>>Multifunction DAQ>>E series'.
About dithering and increasing resolution of your signals, here are good tutorials on our website that should answer most of your questions.
