Some of the smart-serial cards offer analogue input on some channels.

I am using a 6i24 on my current build.
You might want to consider a 7i33TA for high-speed IO and then add a
7i44 to connect a selection of smart-serial cards.
For example, a 7i73 for the control panel can very much simplify control wiring.

I am using a 7i84 (smart serial) for digital IO, and that also offers
some MPG counters and 4 channels of analogue input (at 8 bit
resolution).
If you want more accurate analogue input then there is the 7i87 (also
smart-serial, 10 channels, 12 bit) but for a load meter 8 bits is
probably adequate.
