Volt/Current to RS485 Converter

The N4AIA04 is a module that converts analog readings to digital. The module has 4 input readings. The first 2 (C1 & C2) is used to read 0-20mA, the third channel is used for 0-5V (V1), and the forth is used for 0-10V (V2). The module communicates using Modbus RS485. With the use of the N4AIA04 for example, increases the number of input analog readings for the ESP32 which can only read voltage 0-3.3V.
