The 4-Channel Analog to 12C 13.2 Module is a quad-channel 4~20mA current analogue acquisition module. It has the STM32G030F6 main control chip and a dedicated acquisition chip with isolation to communicate with the M5 host for I2C communication. It supports switching to internally or externally powered wiring via jumper caps. There's an onboard power isolation chip and built-in op amp circuitry that accurately measures external current sensors and provides signal accuracy and system safety. In terms of power supply, the DC-JACK interface and the corresponding DC-DC boost circuit can provide power to the entire device. It's suitable for power system equipment monitoring, motor control, energy management and automation, and industrial process control.
