Expander 24 relay and 64 relay

[bsarevalo]

Hi everyone, especially Hifikat! ... I am finishing a project and we are using 3 KC868-A6 modules ... for the moment everything is going well ... now our client asked us to expand the outputs of module 1 to 24 relays and of module 2 to 64 relays ... Could you recommend good options for this? ... expansion cards i2c, uart...? If you have the products, you can tell us the reference... surely we are going to buy!

i think you can use A32 or A64 board. suggest connect with RS485 or ethernet cable. not suggest use i2c, i2c is not good for extend by wires, that will not stable. Do you must use A6 with relay board by wire connection directly? or just in same network is ok?

We are going to wire the modules, I think RS485 would be fine. Thanks for your answer !

yes, RS485 is ok.
