Billiger IO ausbreitung

[Gast]

Hallo,

Entschuldiging fur mein Deutsch. Es is nicht sehr gut. Ich bin ein neues project gestartet. Ein billiger IO ausbreitung (TCPIP) fur the Loxone. Dies ist mein web-page: https://hackaday.io/project/20602-ch...-for-smarthome
I habe ein Loxone minisever und I mache ein IO ausbreitung fur mein project. Bitte helft mir mit meinem projekt. Ihre ergänzungen sind willkommen. Das ist in kurz das projekt:
* Arduino controller
* Ethernet --> Modbus RTU
* Ethernet --> 1-wire
* Ethernet --> DMX512
* Ethernet --> 64 IO's
Ich brauche software understutzung. Ich bin ein "hardware engineer".

Mit besten Grüßen,
Mark

Hello Mark,

Your project is a nice multi-purpose extension. It might have capabilities for Loxone and Non-Loxone customers to extend their installation.
But, imho, the Loxone Forum might not be the right place to seek for an Arduino firmware programmer. You would be better supported in an Arduino-specific forum.

Regards, Christian

Hello Mark
One problem is the iso distances to the connections, too tight
I also see a problem with the heating of the relays when they are too tight
And for your house: One must build so that everything is insurance compliant
is it so ? I think not

The cheap extension board/billiger IO ausbreitung is finish. It's an open project, so please joint in. Helmut, the board you have seen in the beginning is not mine. I had to have a generic picture for my project. Please have a look at my current board. https://hackaday.io/project/20602
I have done everything to protect the board against ESD and so on and I am hardware engineer for my profession. So this board is developed with professional tools and with my experience as hardware engineer. The sync DC-DC converters have a efficiency up to 90%, so heat dissipation should also be minimal.
The PCB is a very complete solution:
* LCD for status update
* 64 interrupt driven IOs (so capable to detect double clicking)
* DMX512
* Modbus
* 1W
* External I2C
* Wifi or Bluetooth v4.0 (BLE)
* Ethernet connection
The LCD can also display Loxone messages. Main communication will be TCP/UDP messages over the Ethernet device (ENC28J60). I will use my board in my house in the Netherlands.

Everything is open source.

Please have also a look at my Loxone SSR output modification on hackaday. https://hackaday.io/project/25817

Wow! Congrats to this mod! Not for anybody. And loosing any guaranty and certification. But for me it is very important to proof that it would be quite easy to use SSR instead of ancient relays. And the impact to the hardware costs would be a few euros.

Thank you for the congratulations . You can not stop innovation/enhancements. Solid state relay have some advantages. The mean time before failure is much longer for a solid state relay than for a mechanical relay. A heavy duty application for instance would last 2 months with a normal relay and 833years for a SSR (worst case SSR MTBF is 83years). See http://www.crydom.com/en/tech/newsle...0of%20ssrs.pdf
So it's better to use ESD protected solid state relays. I think enhancements that make a product to be more reliable can only improve the product.

Nice Mod

Thank you. I do my best.
