Description
AIN4-20mA Unit
is asingle-channel
4~20mA current analog measurement unit. It adopts theSTM32G030F6
main control chip to communicate with the M5 host throughi2c
. 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.Features
