Output Driver of NI-9477

[jenstl]

What is the output driver for the NI-9476 and NI-9477 modules? I need to model it in MultiSim.

The 9477 and 9476, can source up to 1A per channel up to 20A per module, but the current must AAA be provided from an external source. 

Have a look at the manual of the 9477 of 9476 devices

Check page 8 for a diagram of the configuration

I have seen the documentatin and it does not provide sufficient detail. Driving 1A to ground doesn't say much about the output stage, as that could be a relay, transistor, MOS-FET, or something else. I need to know what the output stage is because I need to know what the voltage is when driven low. It is critical to my application. I need to know what the output driver is, by manufacturer and part number. Then I can easily look up all of the perameters I need to know.
