Hey folks,
me and my team from guh have developed an open source smart home software called guhIO. github.com/guh/guh/wiki (http://github.com/guh/guh/wiki)
Last week I've setup a new project named guhPLC. It's not realy a PLC it is more a hardwired smart home server. It is mainly designed for single-famility house builders - it can be mounted on DIN rails like you can find in an electrical cabinet.
Specs:
- A13 SoM
- LAN - ENC28J60
- STM32 Microcontroller
- 24V DC IN
- 8 Digital In - 24VDC
- 8 Relay - 5A/240V AC
- 4 Analog In 0-10V
- 4 Analog Out 0-10V 20mA
- RS-485
You can get the schematic and board files at https://github.com/guh/guhplc (https://github.com/guh/guhplc)
Check it out! :D
Cheers,
Bernie
