Eletechsup OEM ODM

 I'm writing to inquire about a possible OEM design.  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).
