Can I use one MC050-010 PVG Power pin (p34-36) to power more than 3 PVEA coils, say, 5? The controller output pin is rated 3A while the PVEA coils draw only 0.17A.

Yes, since these are Digital outputs.
It's not possible with PWM outputs.

But whats about driving PVEH at voltages at 10V (machine starting for example)?
At 24V you have 0,3A, at 12V: 0,57A, at 10V: 0,7A (10Watt) !
Now, if you drive 5 PVEHs, the current will be 3,5A, which is to big!
I think, you must not drive more then 4 PVEHs on a digital output PIN.
PVEA will be no problem because of lower current.
Is this OK?
-
I think this should not be a problem because you only power on the PVE when a valve is actuated.
How great is the likelihood, that you use 5 valves at the starting of the machine?
-
It is not only by starting a machine.
Perhaps there are several switches between Batterie and controller, or long cables.
I have seen a lot of this in practice.
So, if you use outputs, which are combined, I think, 3 PVEHs are enough.

By using paired outputs, the maximum current at 70°C (in the box!) is 4A for both!
One output can only drive 2A.
If you have 3 PVEs, it is 0,7A/PVE!
