9401 pull-down value

[garyg100]

According to http://www.ni.com/pdf/manuals/374068f.pdf 

Each channel also has a pull-down resistor and includes
overvoltage, overcurrent, and short-circuit protection. Refer to the
Specifications section for more information about input thresholds
and overvoltage protection. Refer to the Overcurrent Protection
section for more information about overcurrent protection.

What is the value of the pull-down resistor? 

Thanks!

Hi garyg100,

The approximate value of the pull-down resistor is 47kOhm. But the information which may be more useful to you would be further down the manual which gives the input current and input capacitance,which can be found here.
