SCXI-1162HV Input Sensitivity different from previous modules

[steve booth]

I have a number of SCXI-1162HV modules in a chassis, purchased approx. 3.5 years ago. My nre SCXI-1162HV modules only require a fraction of the current required by the originals to indicate a '1'.
Is this important ? We are looking at 2uA to a previous 30uA. Many thanks, Steve Booth

Steve,

It is not the current that causes the SCXI-1162HV to register a "1", it is the voltage level. As long as the voltage is above 2V DC it will register a "1". I have attached the specs concerning the voltage levels below.

You should not be concerned as long as the module is working correctly in relation to the input voltage levels.
