ASDU-L20have4Road independent Ethernet interface,8Road isolationRS485Interface, expandable4GFunction, supportRS232giveOTG-USBEquipment debugging. Support data storage and management, with built-in multiple international and domestic communication protocols as well as proprietary communication protocols from other device terminal manufacturers, and support for protocol customization and development，Provide configuration software for quick configuration and data and protocol management.

ASDU-L20The communication management machine is used as the main control substation and front-end processor of the integrated automation system, forming the middle layer of the automation system. It communicates with various systems such as the main station and communicates with terminal devices within its jurisdiction, completing the collection and forwarding of terminal device data. It can completely replace the functions of microcomputer substations or front-end processors. Widely applicable to distribution automation systems, dispatch automation systems, and large-scale comprehensive automation systems with high requirements.
