pxi 6515 output not working in NI Max

Hi,

I am trying to test my pxi6515  digital io and i cant get it to output a voltage in the SCB100A terminal (P7.0 and P7.1) I am operating it through NI Max, Vcc is connected to 24V (pin 96) and ground to P7.GND (pin 97), . The digital input tests fine in NI Max.

 

Does anyone have an idea what the issue could be? Any settings i need to change? The pin numbers seem to be correct.

 

Cheerio, Peter

Hola Peter,

 

All the 32 output lines form the 9515 are sinking, this means that you wont see a voltage at its output when it is turnned ON because it provides you with a path to ground.

With sinking outputs you should wire the +24Vdc to the device and the ground from the device to the output pin of the digital io card.

Of course I don't know how you connected the circuit, i'm just guessing

Hope this helps.

Hi Antoniooh,

Peter
