rs485 to 0-20ma output - common ground type

Overview

The mcu uses Xiaohua Semiconductor's hc32f005, the analog output uses GP8212S, and the 485 isolation chip uses CA-IS2092W. It is a domestic design. The specific parameters are as follows:
1. rs485 uses CA-IS2092W with power isolation. Complete isolation to 485.
2. Wide voltage power supply, internal integrated voltage-boost and buck module, allowing the system to work in 24v state.
3. This module is used to simulate analog output.

I have an article introducing and testing performance in detail and posted it on the public account "FunIO". If you are interested, you can follow it.
