Product description: 4-channel 4-20 mA to I2C analog signal converter - M5Stack M133
M5Stack M133 is a four-channel 4-20 mA analog signal to I2C signal converter . It is based on the STM32G030F6 system , which is responsible for communication via I2C with M5Stack and collects measurement data from the module's analog input connectors. It is also equipped with a power supply isolation system and an op-amp system for measuring data from analog current sensors. The converter will work well in industrial applications where current signals are used, including : in motor controllers or all industrial sensors . The module is compatible with popular programming platforms such as Arduino IDE and UIFlow , which facilitates integration with various systems.
The manufacturer has prepared detailed technical documentation for the product, which helps in starting work with the converter.
4-channel 4-20 mA to I2C analog signal converter - M5Stack M133.
M5Stack M133 allows you to convert a current signal into an I2C signal.
Characteristic features of the converter
- Converts an analog current signal in the range from 4 mA to 20 mA into a digital I2C signal
- It communicates with the M5Stack main module using the I2C protocol
- It is equipped with an STM32G030F6 chip, 64 KB Flash memory and 8 KB SRAM memory
- It has the ability to switch between internal and external power supply using a jumper
- It offers support for 2- and 4-wire sensors, with the ability to be easily switched using jumpers
- It has a built-in galvanic isolation system for system security
- It is compatible with programming platforms such as Arduino and UIFlow
Four available signal channels
This module offers four independent signal channels , which allows simultaneous monitoring of multiple power sources or different points in one system. This multi-channel functionality is important in applications where it is necessary to track several current parameters simultaneously.
