is it ok to hook up two voltage analog outs in serial?

[Fibo]

ok... I have a FieldPoint FP-210... basically an analog voltage out, 0-10V out, 200mA per channel (with added external power supply)... my question is... can I hook two channels in series?  Like the way I can put two AA batteries in series... and then double my voltage?  and then control my two seperate channels and the sum of the voltages would be would I subject my load to?

thanks!

No, you can't.  The channels all share the common side of their outputs.  If you tried to hook them in series, you would wind shorting out one output relative to ground.

The reason you can do it with batteries is that there voltages are floating.  There is no common reference between the negative terminals of the two batteries.

Raven keepin me straight, again!  Thanks!  You've prevented a bad thing from happening.
