Intelligent Gateway 1 Ethernet 1*RS485

The ASDU-LE1 wireless industrial embedded computer can integrate a highly reliable industrial 4G full-network module or WiFi module, coupled with an efficient and stable power supply solution, providing effective protection for long-term network operation of the wireless module. Simultaneously, the machine also integrates a comprehensive fault recovery processing circuit, effectively solving the self-recovery function required by users in unattended applications.

The main input power supply adopts an industry-leading ultra-wide voltage step-down DC/DC solution, providing users with a DC 9~48V ultra-wide voltage input. The use of a high-efficiency DC/DC step-down circuit effectively reduces heat generation. The lower overall operating temperature further improves the reliability and lifespan of long-term uninterrupted operation, while also contributing to global energy conservation and environmental protection, and reducing carbon emissions.

The ASDU-LE1 industrial embedded computer uses a mature, high-performance 32-bit processor with an ARM Cortex-A7 core and ARMv7-A instruction set architecture. The PCB design fully considers electromagnetic compatibility. To ensure the product meets the stability requirements of industrial equipment, the entire board design adopts full industrial wiring, fully guaranteeing the integrity of high-speed signals and anti-interference performance. Utilizing high-quality PCB materials, it possesses superior stability. Mass production using fully automated surface mount technology (SMT) effectively ensures consistent product quality across batches.

The ASDU-LE1 industrial embedded computer supports ultra-wide voltage AC/DC power input. Its power input circuit employs a unique dedicated circuit design, capable of withstanding lightning strikes under the highest level 4 (4KV) 1.2/50uS-8/20uS combined wave lightning strike test as specified in GB/T 17626.5-2019 standard. Multiple power protection measures, including anti-static, overcurrent, and reverse connection protection, effectively guarantee reliable operation in harsh environments such as outdoor settings.

It integrates a 100M/10M high-speed adaptive network card with three levels of lightning, anti-static, and anti-interference protection, capable of withstanding 2KV differential mode protection under the 10/700uS-5/320uS combined wave test as specified in GB/T 17626.5-2019 standard. The single-channel RS485/RS232 circuit features full electrical isolation. The RS485 circuit employs three levels of lightning and electrostatic discharge protection, supporting the highest level of 4KV protection as per the GB/T 17626.5-2019 standard for 10/700uS-5/320uS combined wave testing.

An advanced, high-security dedicated encryption chip provides professional encryption binding protection for user applications, ensuring reliable anti-theft protection for user development results. Each machine has a unique, tamper-proof physical ID number. Combined with multiple encryption bindings for the user application, application theft is virtually impossible.

Fully compliant with CE, FCC, and RoHS certification standards, the stable hardware design ensures long-term, uninterrupted system operation. Support for a pure hardware timed watchdog makes it suitable for unattended 24/7 operation environments.

The ASDU-LE1 industrial embedded computer runs on a LINUX operating system with kernel version 5.10. External interface drivers are integrated and basic operation demo code is provided. Users only need to focus on application function development, without needing to worry about underlying driver and hardware development.
