M5Stack IO Module for StamPLC
M5Stack IO Module for StamPLC is an electrically isolated IO expansion module designed for the StamPLC host and ideal for industrial environments where high- and low-voltage circuits coexist. The IO module features active analog acquisition channels, solid-state relay outputs, and a mechanical relay output. The device supports signal acquisition from industrial active voltage and current sensors while controlling the on/off state of load circuits. The onboard STMicroelectronics STM32G030F6P6 controller centrally manages external inputs and outputs, address assignment, relay driving, and I2C bus communication over the isolated channel. A hardware DIP switch allows customization of the I2C address, enabling multiple modules to be connected in parallel or in a cascade. M5Stack IO Module for StamPLC effectively suppresses common-mode interference and surge impacts from sensors and field loads, improving overall system stability and making it ideal for industrial automation applications.
