245U-E Wireless High-Speed Ethernet Modem


The ELPRO 245U-E Wireless Ethernet Modem is a robust, license-free wireless 802.11 standards-compliant transceiver capable of high‑bandwidth communications. Operating at 2.4 GHz or 5 GHz and up to 400 mW, the ELPRO 245U-E is optimized for throughputs of up to 108 Mbps, providing robust and secure two way wireless communications in challenging indoor and outdoor environments typical of industrial monitoring and control applications. Capable of operating in access point/client configuration, functioning as a network bridge/router, or serving as a serial server (RS‑232/RS-485), the ELPRO 245U-E offers node-to-node deterministic mesh network repeatability for greater range and multiple channel spacing options to increase network scalability. Integrated Modbus server capability allows seamless I/O expansion through the use of ELPRO 115S expansion modules.
