Advanced Voltage DataLogger - 20 Channel

Developed By

SlightGen Solutions

Product Description

The 20-Channel Voltage Data Logger is a high-precision industrial-grade data acquisition system designed primarily for battery manufacturing plants, testing laboratories, and industrial R&D environments. It is an advanced upgrade to the earlier model. Check more about the earlier model here.

This enhanced version introduces:

• Improved measurement accuracy (up to ±10 mV, comparable to premium instruments like Fluke multimeters).
• Robust software integration for real-time monitoring and centralized data management.
• Smarter data handling with auto-upload, offline storage, and auto-calibration features.
• Fast Measurment High speed measurement of all 20 channels.

With its combination of industrial durability and laboratory-grade accuracy, this logger is the perfect tool for applications where reliable, multi-channel voltage monitoring is critical.

Product Architecture

The system is built with:

• 20 isolated voltage measurement channels for independent monitoring.
• Ethernet / Wi-Fi connectivity for centralized data management.
• Onboard SD storage for offline logging and data redundancy.
• SQL server integration for enterprise-scale data collection and analysis.

Working Principle

The data logger continuously (or based on external triggers) measures voltages across 20 independent channels and transmits the results to a central SQL server over Ethernet or Wi-Fi.

If server connectivity is lost, the system automatically switches to onboard SD card logging, ensuring no data is lost. Once the connection is re-established, all stored logs are uploaded to the central database.

A dedicated Windows-based software application enables operators to:

• Monitor real-time voltages across all 20 channels.
• Configure logging parameters such as interval, triggers, and alarm thresholds.
• Review historical data for batch analysis.
• Export logs and generate reports for quality assurance and compliance.

This Utility is customizable as per customer need.

Built-in Protection & Accuracy Enhancements

• Overvoltage and reverse polarity protection ensures robust operation in industrial setups.
• Short-circuit and overcurrent protection safeguard against electrical faults.
• Auto-calibration functionality maintains accuracy over long-term operation, eliminating the need for frequent manual recalibration.
• Achieves ±10 mV tolerance (±0.2% accuracy) — comparable to industry-standard multimeters like Fluke, but in a multi-channel, automated logging format.
