Hi everybody,
I just wanted to share here my test results on IONO board.
My initial review can be found here: http://souliss.net/articles/Iono-Relay-Board/
and tonight I was able to invest some time to really use the board.
I got the IONO solo (only the I/O board) and no arduino.. and since I was willing to quickly test it I used what I had home.
An arduino UNO R3 and a Ethernet Shield.
Moreover I don't really like the Arduino Ethernet board because you need a USB->RS232 converter for the programming.
Of course IONO can host UNO + Eth Shiled but unfortunately the DIN enclosure is not designed to host two boards one at the top of the other.. but I managed to have them with a couple of simple tweaks.
I reduced a bit IONO headers length
This was enough to fit the two boards in
and then I created some space for the USB connector
having this final result.
Good enough for me..
except my Eth Shield uses A0 and A1 to handle the SD card.. even when the card is not fitted so I cannot use the first two inputs in this configuration unless I make some really ugly jumpers from UNO to IONO bypassing the ETH shield.
So.. in case you wish to repeat my experiment I suggest you to purchase the Eth shield version not using A0 and A1 for the SD.
I gave the board a 15V ac power supply from a very cheap transformer I had on the shelf..
The board powered up immediately, great.
I had some fear to plug the USB from my computer to UNO having the power supply plugged to the 15V ac..but nothing odd happened.
So I confirm you can have both cable connected with no issues for you board and you PC.
First I loaded the basic Hello World example sketch provided in Souliss available here together with others.
The sketch is simply working smooth, no surprises.
Nice to hear a powerful "clack" when relays change status, I was used to cheap 5V relays almost making no sound.
These relays are of good quality and driven in a clever way... powered just for status change to increase lifetime, reduce power consumption and avoid over heating.
They are very large latching relays with rated load of 16A at 250V, up to 6,000 VAC dielectric strength between coil and contacts and 10 kV impulse withstand voltage.
Perfect to drive inductive loads, cheap relays for example are not suitable to drive electric motors like shutters actuators... but these yes !
The Analog Output seems to be very stable, driven by a T19 logics you have a nice slider in SoulissApp from 0-100% you get 0-10V ... accurate enough,
Detailed specs on IONO analog outs can be found here
The cherry on the cake are big removable screw terminals that guarantee a very easy installation and maintenance.
Output terminals are big enough to fit a couple of 1mm^2 wire in the same hole.
The overall manufacture quality of the board is clearly above the average among the DIY world.
These boards are not cheap but the cost is surely not high for what you get.
This board will find its place in my garden for controlling watering (4 zones) and lighting (2 zones) connected via Ethernet with the rest of the apartment (currently 125 slots).
The idea is to avoid watering if rain is forecasted and adjust the watering with the insulation/temp/humidity.
I'll keep you posted on this.

Great, hope to see your final device as tutorial :-)
