MC050 PVG Power output limits
oiltronic:
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.
Stefan:
Yes, since these are Digital outputs.
It's not possible with PWM outputs.

Marbek_Elektronik:
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?
Quax76:
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?
Marbek_Elektronik:
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.
