I have 24V input voltage given between volatge and common . Across Vsup and Common , i have given 24 V. I have connected an LED with 4.6Kohm resistance to the DO1 output on NI9476. I see that LED is continously ON. The voltage across LED is 7.365 VDC and when i set the output pin as high of DO1 , the voltage across LED is 8.71 VDC. The difference between High and low voltage is very less.
Can you suggest what is the problem with this? I want to be 0V and 24V
