Advantech EKI-1221CI-DE Modbus Device Server for Reliable Ethernet and Serial Communication

The Advantech EKI-1221CI-DE is a high-performance device server designed to seamlessly integrate serial devices with Ethernet networks, supporting robust Modbus TCP and Modbus RTU/ASCII protocols. Featuring two 10/100 Mbps Ethernet ports, this device offers LAN redundancy, ensuring continuous network operation even in the event of a port failure. Its versatile communication options include software-selectable RS-232, RS-422, and RS-485 interfaces, accommodating various serial device configurations and baud rates up to 921.6 kbps. This flexibility allows users to tailor the device to their specific application needs while maintaining high data transfer rates. The EKI-1221CI-DE supports multiple connection modes, with up to 16 connections per serial port in client mode and 64 sessions in server mode, enabling complex network architectures and efficient data exchange. Its support for agent mode provides the fastest response times, ideal for time-sensitive industrial applications. The device also offers comprehensive redundancy features, including power, Ethernet, and device redundancy, to enhance system reliability and uptime. The automatic RS-485 data flow control ensures smooth serial communication, while the wide operating temperature range makes it suitable for industrial environments. Additionally, the "CI" model provides added protection with line-to-line (1 kV) and line-to-ground (2 kV) surge protection and supports isolation, making it ideal for harsh industrial conditions. Designed for wall mounting, the EKI-1221CI-DE is compact yet durable, backed by a five-year limited warranty. Its compliance with RoHS standards demonstrates its commitment to environmental sustainability. Whether used for building automation, industrial control, or remote device management, this device server ensures high availability, security, and seamless integration of serial devices into modern Ethernet networks.
