· Product Introduction

The SPC2080-MD series modules are multifunctional, composite serial port servers that convert 2/4/8-channel serial port data to Ethernet data. They feature various MODBUS gateway modes, as well as TCP Client, TCP Server, UDP Client, UDP Server, MQTT, and HTTP IoT gateway modes, meeting the networking needs of various serial devices and PLCs. They support serial port baud rates up to 115200bps and are easily configured via host software.

This series of modules not only provides conventional serial port server functionality, converting standard RS485 serial port signals into TCP/IP signals, enabling bidirectional transparent data transmission between RS485 serial ports and TCP/IP network interfaces, but also offers MODBUS gateway functionality, converting between MODBUS TCP and MODBUS RTU protocols. This allows serial devices to connect to Ethernet for data communication, significantly reducing serial device wiring and expanding communication modes and distances. 

This product requires independent power supply and adopts DIN35mm standard rail installation. It is easy to install on site and flexible to use, and can cope with various on-site applications.
