For instructions details, please refer to the ''R4CVA02 R4IVB02 MODBUS RTU Commamd''
This is a 2.54MM pin header version of the RS485 0-5V/0-10V/4-20MA/0-20MA voltage/current collector.
A 12-bit ADC is used to collect the voltage signal, but the data read is voltage/current data with a unit of 0.01V/0.01MA.
The size is kept to a minimum while meeting the functional performance. It can be used as a core board and embedded into the base board.
