I could run simulations in my mind on what configuration would turn out how and how it would affect my further design, yadayadayada. Lets get some facts down about what I need, want to achieve, or simply have decided (be it out of lazyness, sheer desperation or from flipping a coin).
Features:
- DIN rail form factor
- AtMega2560 based
- USB/FTDI
- RS232
- RS485
- Ethernet
- 12V supply voltage
- nice to have: LED Indicators for IOs
Additional Features:
- Relays (230V)
- Power Outputs 5V/12V 1A
- Optocoupler IOs
- nice to have: all IOs optically isolated
- nice to have: debounced limited outputs for buttons
As I write I started pestering reddit with my questions on [possible circuits] and [requirements]. Let’s see what it leads to :)
