Switching CAN Bus through USB-6525

I want to use my USB-6525 to switch CAN, but I don't want to use external relays. I plan on using 8 Mbaud with XNET, but I'm unsure if the transistor in the optocouple can handle those speeds.

 

Does anyone have the specs of that optocoupler or know if this is possible?

Hi Zilenc

 

What optocoupler are you talking about?

The output of a 6525 uses a photo-transistor, right? or photo-diode I forgot. I know this signal will pass through mechanical contacts, just unsure if it will with the 6525 outputs direct.

Depending on the technology it was built, an optocoupler can handle 8MHz or more easily. 

 

in this case, you have to consider that you will use solid-state relays, and these are made for high voltage isolation and low frequency uses.

 

If you see the datasheet, you will find, ( http://www.ni.com/pdf/manuals/371818b.pdf

Switching rate (90% duty cycle) ............5 operations per second

Switching rate, isn't that related to toggling the output on/off? Which is irrelevant for this case, as I will have it turned on or off during and after comms.
