2CH-RS485-ETH, 4CH-RS485-ETH, and 8CH-RS485-ETH are RS485 IoT gateways specifically designed for industrial environments. It integrates multiple functions, including a serial server, Modbus gateway, MQTT gateway, and RS485 to JSON converter.

It has 2, 4 & 8 RS485 ports to choose from and an Ethernet port. It adopts DIN rail installation mode, which is easy to install. Compared with the traditional desktop serial port server, the width is reduced to about 1/4 of the original compact size. Adopt terminal-type power supply access with a 9 ~ 24V wide voltage input.
