Module13.2 AIN4-20mA
Description
Module13.2 AIN4-20mA is a four-channel 4 ~ 20 mA current-type analog acquisition module. It uses the STM32G030F6 main control chip and a dedicated isolated acquisition chip, communicating with the M5 host via I2C. It supports switching between internal or external power supply through jumper caps. The onboard power isolation chip and built-in operational amplifier circuit ensure accurate measurement of external current sensors and the accuracy of the signal and system safety. The DC-JACK interface and corresponding DC-DC boost circuit provide power to the entire device. It is suitable for power system equipment monitoring, motor control, energy management, automation, and industrial process control.
