Unit AIN4-20mA
SKU:U162
Description
Unit AIN4-20mA is a single-channel 4~20mA current analog measurement unit. It uses the STM32G030F6 main control chip and communicates with the M5 host via I2C. It supports switching between internal or external power supply wiring modes through jumper caps. The onboard power isolation chip and built-in op-amp circuit can accurately measure external current sensors, ensuring signal accuracy and system safety. It is suitable for fields such as power system equipment monitoring, motor control, energy management, and automation and industrial process control.
