Data Logging Module

The Data Logging Module is an embedded electronic component within Industrial Systems that continuously acquires measurement data from connected sensors and equipment, converts analog signals to digital format, timestamps the data, and stores it in non-volatile memory for subsequent analysis, monitoring, and quality control purposes. It is designed for integration into industrial control cabinets or DIN-rail mounting, operating within a wide input voltage range of 9–36 V DC and consuming no more than 5 W at 24 V DC. The module provides 4 to 8 configurable analog input channels with 16-bit resolution, supporting sampling rates from 1 to 1000 Hz per channel. Data is stored in industrial-grade flash memory with capacities ranging from 8 to 32 GB, ensuring reliable retention even in harsh environments. Communication interfaces include RS-485 and Ethernet, with Modbus RTU/TCP protocol support for seamless integration into existing industrial networks. The module is designed to operate in extended temperature ranges from -40°C to 85°C, with storage temperature matching the operating range, and it withstands relative humidity from 5% to 95% non-condensing. Its ingress protection rating of IP65 to IP67 makes it dust-tight and water-resistant, suitable for demanding industrial settings. The compact dimensions of 100 x 75 x 30 mm and a weight of ≤300 g facilitate easy installation. A real-time clock maintains timestamp accuracy within ±2 seconds per day. The module is built with a printed circuit board, microcontroller unit, and flash memory chip, ensuring robust performance. For procurement and verification, it is essential to confirm model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges. The module's operating principle involves signal acquisition, analog-to-digital conversion, timestamping, and storage, with low power consumption and optional communication for data retrieval. It is a critical component for data logging in industrial automation, process monitoring, and quality assurance applications.

The module receives electrical signals from various sensors (temperature, pressure, flow, etc.) through input interfaces. These analog signals are processed by an analog-to-digital converter (ADC) with 16-bit resolution, converting them to digital data. A real-time clock adds precise timestamps to each sample. The digitized and timestamped data is then stored in non-volatile flash memory or SD card storage. The module operates on low power consumption, typically ≤5 W at 24 V DC, and may include communication interfaces such as RS-485 or Ethernet for data retrieval and integration with control systems. The sampling rate is programmable from 1 to 1000 Hz per channel, allowing flexibility for different application requirements. The module is designed for continuous operation in industrial environments, with robust construction and protection against dust and water ingress.
