KC868-A4 Serial Ports and Scl Sda ? and Voltage range of 4-20mA ports

Posted by: gokhan - 01-06-2022, 08:55 AM - Forum: KC868-HxB series Smart Controller - Replies (1)

Does KC868-A4 model control card support to connect Nextion Screen by using Tx2 Rx2 of ESP32
or connect I2C LC by using SCL SDA ?

I looked for but I think KC868-A4 doesn't have SLC SDA and TX2 RX2 ports ? İf it has could you show us ?

Secondly I have 4-20mA sensor output and voltage of sensor terminals is 24V
what happens if I connect 4-20mA sensor output to KC868-A4 4-20mA ports
does the 24V of supply voltage of sensor damage the ports of KC868-A4 ?

Huh

Controlling all wall sockets using Kincony products

Posted by: viktor - 01-05-2022, 09:23 PM - Forum: KC868-HxB series Smart Controller - Replies (5)

Hi guys,
I follow Kincony products for some time and really like all the features they bring. I'm not electrician, have no experience with smart installations yet, but have master's from computer networks. As we are moving to a new flat that requires complete re-construction, I'm playing with an idea to buy Kincony products and turn that place into a smart one. I'm not fan of wireless connections due to security, so was thinking about wiring everything - around 10 lights, 15 wall switches, 30 wall sockets and 4 external curtains. LAN network would be OK for me. I struggle with few things and maybe somebody in this forum can help me to answer them? Sorry If my questions are lame...

1. Is above described scenario OK for Kincony products?
2. I'm located in Europe and our sockets have max load of 16A. I see that KC868-H output ports have max load of 10A. So how can this control 16A sockets? Should I use those Omron relays that support 16A? If so how to chain them?
3. If I want to be able to turn on/off each wall socket separately, what products should I use and how to wire them? Max output ports I see in the list is 32, so seems like I need to do some chaining? Also, when it comes to connection, do I need to run separate L wire between relay appliance and sockets? When it comes to N and GND wires, those can be chained from one socket to another?
4. I understand that wall switches will only use 12V. Initially I thought they only use some simple data bus wire to send signal about pushed button to controller. But looking at the pictures of some Kincony switches in articles posted here, there are many ports on the back side. So how does this actually work and how many wires do I need to run to each wall switch?
5. Finally, which products should I buy to achieve all of this? It is clear that I will need to ask electrician for installation. But I would like to understand this myself as well.

Thank you.
