Discover the M5Stack PLC Controller with M5StampS3 – your compact and powerful solution for industrial automation and IoT projects. This versatile device combines the processing power of the ESP32-S3FN8 with extensive input and output options, as well as modern communication interfaces. With 8 opto-isolated digital inputs and 4 relay outputs, you can reliably control a variety of sensors and actuators. Thanks to Wi-Fi support and the integration of PWR-CAN and PWR-485 interfaces, the controller can be seamlessly integrated into existing networks. A 1.14-inch color display, user-friendly buttons, and an integrated buzzer enable direct interaction and status monitoring. The wide input voltage range of 6 to 36V DC and DIN rail mounting make it ideal for use in demanding industrial environments. Additional features such as a microSD card slot, temperature and current sensors, and an RTC provide enhanced functionality and reliability. Program the controller flexibly with UIFlow 2.0, Arduino IDE, or ESP-IDF to efficiently and professionally realize your projects.
