AIN4-20mA Module 13.2

SKU:M133

Description

AIN4-20mA Module 13.2 is a quad-channel 4~20mA current analog acquisition module. It adopts the STM32G030F6 main control chip and a dedicated acquisition chip with isolation to communicate with the M5 host for i2c communication. 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. In terms of power supply, the DC-JACK interface and the corresponding DC-DC boost circuit can provide power to the entire device. 'Suitable for power system equipment monitoring, motor control, energy management and automation, and industrial process control'.

Schematic

Jumper cap connection and instructions

If your current sensor already has an external power supply, the jumper cap is connected as shown on the left
If your current sensor does not have an external power supply, connect the jumper cap as shown on the right, and connect the interface of AIN4-20mA Module 13.2 to the appropriate external power supply as needed.
