We are using some of your boards for facility automation (lighting etc). I'm looking for an 8ch 0-10V output + 8ch 16amp relays with ESP32 or modbus/RTU or modbus/IP interface. Do you have anything like that currently? Basically ETAIC04 ETVOD08 ETIOE16 Digital Analog Ethernet Remote I/O Modules Mod
but combined with AMVOL08 8 Channel Analog Output 0-10V 0-5V AO Module RS485 Modbus RTU (and no need for so many NPN inputs).
Specs: ESP32 (wroom devkit c v4 on socket),
(8) DO 13 Amp Hongfa Relays,
(8) Analog Ouput 0-10V,
RS485 (to ESP32),
2 Digital inputs opto-isolated.
The PCB will likely need to be 4oz copper w/ thick traces for the relays. It will need to handle 13 amps at 120/240VAC continuously for years.
yes , we can OEM for you .
