Im an using a 6221 DAQ card with a BNC-2110 Terminal Block connected to it. For the digital I/O block to the terminal provides an extra 5V input. Unfortunately I don't seem to find any information as to whether this provides extra drive current to the TTL signal or not. Is there an internal driver in the terminal block, or - if i need to connect external relays to the digital output - do i still connect a current driver in between?
Thanks,
Wolfgang

Thanks for the quick response. I indeed did not catch it that it is an output, not a 5 Volt input.
No problem, i will add a signal driver - was just hoping to be able to take a shortcut.
Thanks again,
Wolfgang
