Difference between DOUT and DOUT/PVG Power Supply pin

[spittet]

Hi,

In a OX024-110 IO module, what is the difference between a DOUT pin (ex: C1p09) and a DOUT/PVG Power Supply pin (ex: C1p10) about supplying power to a PVES valve coil?

I want to power multiple PVES valve coils from a single digital output pin.

Can I use either a DOUT or a DOUT/PVG Power Supply for this?

If yes, why is there such a distinction between these two types of pins? Why dedicated PVG Power Supply pins exists?

Also, I was being told that I can only power up to 3 PVES valve coils from a single digital output pin. But, looking at the datasheet of the PVES, the supply current will be 560mA @ 12V.
So, for a digital output pin that can supply up to 3A, I should be able to power up to 5 PVES valve coils (5x 0.56A = 2.8A), isn't it?

Hello,
In the OX024-110 Data Sheet , you can read : "Use care when wiring mating connector. Pinouts listed are for device pins. Each DOUT/PVG power supply can power up to three PVG sections concurrently. One OX024-110 output expansion module can drive a maximum of six PVG valves concurrently."

Have a nice day

I'm still interested about the reasons for this limitation.
Each output can drive up to 3A.
Each PVG valve can consume up to 0.56A (PVES). So 6x0.56A = 3.36A. The whole module can source up to 32A max for all the combined outputs.
Why is it limited at such a low number of PVG valve per pin and per OX module?

Also, I'm still interested about the difference bwtween the DOUT and DOUT/PVG Power Supply pin.

Please look to the BTS728L2  from infineon. I have opened  controllers and io-modules and find this as output MosFet.
There are to MosFets in one IC.
Because of temperature the maximum load current is 6A (4A at 70°C) (both channals together.)

There is no difference between PVG Pwr and only DOUT.
 For example look at MC050-110: Here is C1p33 and c1p34 one IC!
(C1p31 and c1p32 are one Power Switch für example! and so on!)
C1P31   DOUT
C1P32   DOUT

C1P33   DOUT
C1P34   DOUT/PVG Pwr

C1P35   DOUT/PVG Pwr
C1P36   DOUT/PVG Pwr

C1P37   PWMOUT/DOUT/PVGOUT

C1P38   PWMOUT/DOUT/PVGOUT
....

If you power PVE Valves you have to consider the capacitors in it.
Older PVEs have had a big capacitor. Since about 15 years the capacitor is lower.
The smart Power Switch have to power the capacitors and the current protection should not turn off. Thats the reason.
Danfoss have to tell us, what is the maximum number of valves.
