SCB-68 Pin#8 (+5V) not working

[bharathsiva]

Hello,

I am using PCIe-6321 DAQ and SCB-68 connector block to connect two stepper motor drivers and drive the stepper motors. I need to provide +5 volts to my driver in order to power the emitter diode in the opto-isolators in the drivers. I am able to get +5 volts from pin 14 of the SCB-68 but I am unable to get the +5 volts from the SCB-68. The Quick Reference Lable states the pin 8 as +5V, Fused. Can anyone suggest me what I am supposed to do in order to obtain the +5 volts from pin 8 of the SCB-68.

Thanks,

Bharath J S

So you can read 5V from pin 14, just not pin 8?  You may have a blown fuse on your DAQ board.  I'm not sure if there are seperate fuses for each output.

Yes I can read 5V from pin 14 but not pin 8. If the fuse is blown on the board, is it possible to change it.

According to the data sheet, it's a self-resetting fuse. Have you checked pin 8 at the DAQ card itself?
