Ethernet modem, RS-485, TCP/IP compatible. Modbus 230V communication.

The ETH-GTW-230V is an industrial communication gateway designed for converting RS485 (Modbus RTU) signals to Ethernet (Modbus TCP/IP) , allowing the integration of devices into IP networks and remote monitoring systems.
This version operates on a direct 230V AC power supply , simplifying installation in electrical panels without the need for additional power sources. It is ideal for connecting equipment such as energy analyzers, controllers, or automation devices to local networks or the internet.
The device allows the connection of up to 10 devices via RS485 bus , acting as a bridge between serial communication and an Ethernet network. It also includes an integrated web interface that simplifies network configuration, communication parameters, and system monitoring.
