1. StamPLC 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 2. In terms of control, StamPLC offers 8 -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 sensors and actuators both simple and reliable 3. 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 4. 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 5. To withstand harsh industrial environments, StamPLC supports a wide voltage input (DC 6-36V) and is designed for DIN rail mounting to 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 (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. Precautions: The power supply output pins for StamPLC's PWR-CAN and PWR-485 are direct connected to the main input power. Therefore, during operation, please that the input voltage matches the power requirements of any connected external devices. For example, when using StamPLC to control Unit Roller485 or Unit RollerCAN, it is recommended to maintain the input voltage within the DC 6-16V range to prevent damage caused by voltage mismatches. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
