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. StamPLC 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. StamPLC supports a wide voltage input (DC 6-36V) and is designed for DIN rail mounting to ensure secure installation; the built-in Micro-SD card slot. 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. This product is suitable for industrial automation, remote monitoring, smart manufacturing, and other applications. Power supply precautions: Precautions: The power supply output pins for StamPLC's PWR-CAN and PWR-485 are directly connected to the main input power. Therefore, during operation, please ensure that the input voltage matches the power requirements of any connected external devices. Note:Due to different production batches, there are differences in printing screen printing, which does not affect the use.
