1. OUTLINE
Stam PLC is an IoT programmable logic controller designed for industrial automation and remote monitoring. The product is based on the StampS3A control module, which not only delivers powerful processing capabilities but also provides efficient wireless connectivity. In terms of control, Stam PLC offers 8 opto-isolated digital inputs and 4 relay outputs (supporting both AC and DC loads), along with a GPIO.EXT port and 2 Grove interfaces, making the integration of various sensors and actuators both simple and reliable. Meanwhile, through the onboard PWR-CAN and PWR-485 interfaces, the device can be seamlessly integrated into industrial fieldbus networks, enabling remote data transmission and centralized control. For human-machine interaction, the product features a 1.14-inch color display, a RESET/BOOT button, 3 user buttons, and a buzzer, which facilitate real-time parameter configuration and status monitoring, and can alert users in the event of anomalies. To withstand harsh industrial environments, Stam PLC supports a wide voltage input (DC 636V) and is designed for DIN rail mounting to ensure secure installation; the built-in Micro SD card slot further facilitates data storage and firmware updates. Additionally, its environmental monitoring system integrates an LM75 temperature sensor and an INA226 voltage/current sensor for real-time feedback on device operation, while the RTC (RX8130CE) module ensures accurate time synchronization and log recording. The factory firmware automatically uploads data to M5’s EZDATA cloud platform, generating monitoring pages and offering users convenient remote cloud access and control. This product is suitable for industrial automation, remote monitoring, smart manufacturing, and other applications.
