RE: 4-AO 0-10V extension does not bring 0-10V on all ports
Hi,
power supply is 24V DC, connected in common. I thought the limit is 36 V ...
i connected 2 actuators, which have an 0-10V input and runs with 24V AC,
Model Honeywell M7410E1002 and M7410E1028best regards

RE: 4-AO 0-10V extension does not bring 0-10V on all ports
Hi Pablo,
i thoiught i had the correct cabeling from the beginning, but i was not sure.
So i ordered 2 more 4-AO 0-10V extensions and got them last week.
I double checked everything and test every AO-Port and everything worked
as excepted. It run's like a charm for 4 days ... until now.
The same effect occurs again, but now 3 ports of the extension does not
work anymore. 2 of them show on Analog-Out 24 V all the time. 1 shows
always 0V. The 4. port still work's.
As i got the same problem with the 2nd extension board, i don't think, that
i made a fault on the first extension board.Because i used the UniPI with the extension for control heating , i now run
into big problems because of the not working extension. -
RE: 4-AO 0-10V extension does not bring 0-10V on all ports
By the way, could it be, that CH0 and CH1 are interchanged.
It i write adress 200 on the pca9685 then CH1 is set not CH0.
CH2 and CH3 are set correctly. Or is it a problem with my
extension board ?best regards,

4-AO 0-10V extension does not bring 0-10V on all ports
Hi,
i am using a 4-AO 0-10V extension and i use 24V DC as AOV on all Ports.
If i now set 100% to all of the AO, i can measue on 2 ports 10V (like it should
be), but on 1 Port 24V and on the other 21V. These 2 faulty output voltages do also
not change, if i change the board trimmer.best regards,

RE: Single Power Source Problems
JP1 has been mounted, sorry was faulty information.
But finaly i found the problem: 5V GND was not connected
to the UniPI power plug, only on the mini USB.
Thank's for you help.best regards

RE: Single Power Source Problems
i will send you the serial number's and some pictures later as i am not locally.
Just to be sure, that i do not make a fault:
- I connected the RasPI to the UniPI only with the flat cable
- Only the UniPI is connected to the 5V Power
- JP1 is unmounted
Is that right ?
best regards,

RE: Single Power Source Problems
I measured the voltage on the pinout of UniPI without the cable,
that's what i've done.
Only the UniPI is connected to the power, i want to avoid the
dual sourced power.
The cables to the DR-15-5 are also ok.Do you have the same effect ?

RE: Single Power Source Problems
The 2.1mm plug is from you and is connected to the DR -15 -5, so it should run,
but i don't have an extra power supply with the 2.1mm plug.
I measured the voltage between ping 2-6 and 4-6. There is always 0V with and
without JP1 mounted or not. So i think the problem lies on the Unipi, not the cable.Does it run on your side with Unipi and Raspi3 on single power source ?

RE: Single Power Source Problems
Hi Tomas,
that's exactly as i connected the cable. That seem's to be ok, as everything else
(setting/resetting inputs and outputs) does work if i connected the power to
the pi over the mini-USB port.Could you give me the Pins, where the 5V and GND should lie on ?
best regards,

RE: Single Power Source Problems
Hi Thomas,
today i received 1 more UniPi+Raspi 3. It show's the same effect.
Is it right, that there is only 1 cable between the 2 unit's, only the
flat cable ?
Should on the Raspi 3 be an LED on, if i connect power to the
UniPi ?Which one are the 5V and GND pin's ? I am more the software man ...
best regards,

Single Power Source Problems
Hi,
i try to connect the UniPi together with the Raspberry Pi 3 on Singe Power Source,
Jumper JP1 mounted. The UniPi hangs on an Meanwell DR -15 -5 .
Connecting the Power on does not powering on the RPi 3, nothing happens.If i unmount JP1 and connect an extra Micro USB Cable to the Meanwell DR-15-5,
it work's.Is Single Power Mode not availiable anymore ?
best regards
Michael
