hello 

i have kc868-h32b pro, which logical controller board is most compatible with it?

Hi! I am planning to use a KC868-A8 in a vehicle, power by battery. What is the input voltage tolerance of the board? Could it handle like, 10-15 volts, or do I have to add a regulator to make sure it gets exactly 12V?

Hello, please could you list mfr. part numbers compatible screw-in terminal blocks replacement to replace the plug-in ones? 6x 1x9P + 2x 1x5P for digital inputs, 2x 1x9P for analog outputs 0-10VDC and 2x 1x9P + 2x 1x5P for AI and serial.

Is the schematic / PCB layout available for the latest -A8, rev 1.5? I'd like to add Power Over Ethenet to the product...

Hello,
I'm a student at BUT Brno in the Czech Republic at the Faculty of Electrical Engineering. I am interested in IOT. At work, where I go, I want to suggest that we start doing Smart Home on your system. We often do electrical installations, and also consulting projects. I mean, if we learn with your system and implementation in HomeAssistant(We have built a few homes on HomeAssistant) I think we could buy products from you more often. So I would like to design my own smaller smart switchboard at home to show the company that this system has potential. So I guess my situation corresponds to situation B, start a Project.
If you grant the request, I would be interested in the KC868-A4.
Thank you very much for reading.
Sincerely Lubos Chmelař

Rebooting...

How solve it ? Is it hardware problem ?

THX

I have designed a control system for a refit of my boat.

The break panel/control panel will be in the engine room, and would like to be able to turn things on and off at the helm, via a dedicated touchscreen.

There are 11 pumps, I would like to be able to see if they are turned on, for how long and if after a preset time, give out a warning.  

electrical layout

would love some feedback and/or corrections.  Trying to order equipment this week.
