Description

AIN4-20mA Unit is a single-channel 4~20mA current analog measurement unit. It adopts the STM32G030F6 main control chip to communicate with the M5 host through i2c. Supports switching to internally or externally powered wiring via jumper caps. On-board power isolation chip and built-in op amp circuitry accurately measure external current sensors and ensure signal accuracy and system safety. It is suitable for power system equipment monitoring, motor control, energy management and automation, and industrial process control.
