best board with 8 inputs

[ndev]

Hi,

I looked into your website and I like all your board.
Great !

You have so many board, it is difficult to find the correct one.
I have a project for which I need at least 4 boards with 8 inputs and some relays (no more than 6 for each).
I will use esphome with Ethernet.


What could be the best board for me ?
KC868-A8
KC868-A8S
KC868-A8S V2
....

Thanks,

any one you can use, just A8S added RS485 port. A8S v2 added manual control switch on the board, if board broken, also can work with manual control switch to turn ON/OFF relay.

Thanks for the quick answer.

A8S have also switch ?
A8S V2 : it is direct switch ?

A8S have also switch ? A8S have manual control button on PCB, it need firmware to work.
A8S V2 : it is direct switch ? Yes, it's physical switch, work without any firmware.

It is written 12/24 V on board. Is it correct ?
Schematic think to be OK.

A8S power supply: DC12V
A8S v2 power supply: DC12-24V
Schematic follows:

Thanks for all your answer.
I will buy 2 to tests.
I was searching this type of board for 4 years !!

How do we buy 24 V board ?
On the schematic, VDC_IN is connected to all VCC ( relay, analog, ...) How do you manage 12V and 24 V. Is there any special board or everything is OK ?

A8Sv2 just one version, use for power supply 12-24v dc. not have two different version.
because the relay coin is 5v dc. when you use 12v or 24v for power supply, both will convert to 5v for relay's coin.

OK.
Yes I found on schematic that VCC is the 5V ! Great.

Thanks
