System Architecture
DLOG G103 is a specialized industrial datalogger designed for remote field deployment where stable mains power and Ethernet are unavailable. At its core is an ultra-low power 32-bit MCU managing a multi-tier energy system and high-efficiency communication modules. It bridges the gap between field sensors and cloud platforms via 4G LTE Cat 1.
DLOG G103 là bộ ghi dữ liệu công nghiệp chuyên dụng được thiết kế cho việc triển khai tại hiện trường từ xa, nơi không có nguồn điện lưới ổn định và Ethernet. Trái tim của hệ thống là vi điều khiển 32-bit tiêu thụ điện cực thấp, quản lý hệ thống năng lượng đa tầng và các module truyền thông hiệu suất cao. Nó đóng vai trò cầu nối giữa cảm biến hiện trường và nền tảng đám mây thông qua 4G LTE Cat 1.

Multi-tier Energy Management
• Primary Input: 7-12V DC input with high-efficiency buck regulation.
• Tier 1 Backup: Rechargeable Li-ion battery (e.g., 18650) with integrated buck-boost management to maintain stable system voltage.
• Tier 2 Backup: Support for AA primary batteries as an emergency backup layer.
• RTC Backup: Dedicated coin cell to maintain timekeeping even during full system power loss.
Power-fail Protection: Hardware monitors the main rail and notifies the MCU of voltage drops, triggering an immediate safe shutdown and state preservation.
Precision Analog Frontend
DLOG G103 provides a premium analog frontend using high-performance rail-to-rail operational amplifiers.
DLOG G103 cung cấp đầu vào analog cao cấp sử dụng các bộ khuếch đại thuật toán rail-to-rail hiệu suất cao.
AI Specifications
• Channels: 4x high-precision inputs optimized for 4-20mA current loops.
• Accuracy: Enhanced precision with ±0.1% tolerance shunt resistors.
• Excitation: MCU-controlled 11.7V boost rail to provide clean power to industrial sensors.
• Monitoring: Additional internal channels for monitoring input voltage and battery health.
Performance Note: The use of specialized rail-to-rail op-amps eliminates the non-linearity issues found in standard industrial controllers.
Deep Sleep Pulse Counting
Unique capability to count high-speed pulses while the main processor is in deep sleep (Stop mode), dramatically extending battery life for metering applications.
Khả năng độc đáo cho phép đếm xung tốc độ cao trong khi bộ xử lý chính đang ở chế độ ngủ sâu (Stop mode), giúp kéo dài đáng kể thời lượng pin cho các ứng dụng đo đếm.
Metering Features
• LPTIM Interface: Two hardware pulse counters that operate independently of the CPU clock.
• Isolation: Galvanic isolation via high-speed dual-channel optocouplers to protect the MCU from field noise.
• Consumption: Full system draw remains below 2µA while counting pulses.
Safety & Reliability
Hardware Reliability
• Surge Protection: High-energy TVS diodes on all analog inputs and power rails.
• Data Integrity: Automatic data buffering to internal flash during network loss, with overflow to SD card.
• Watchdog: Independent hardware watchdog prevents system lock-up.
Environmental Specs
• Temperature: -20°C to +70°C operational range.
• Enclosure: Supports DIN rail mounting in IP67-rated outdoor cabinets.
