EATON ELPRO 450U-E Wireless Ethernet Modem Model
450U-E Wireless Ethernet Modem
Ultra-long range Ethernet, for reliable connectivity
Description
The ELPRO 450U-E Wireless Ethernet Modem is a robust, licensed and license-free
wireless transceiver capable of ultra long-range communications. Operating at 360
512 MHz, and up to 5.0W RF power, the ELPRO 450U-E is optimized for throughputs
of up to 19.2 kbps, which provides robust and secure two-way wireless communica
tions in extremely challenging outdoor environments over obstructed paths typical of
remote 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 450U-E uses
over-the-air data compression to ensure maximum throughput. Integrated Modbus®
server capability allows seamless integration with smart sensors, RTUs, or I/O expan
sion through the use of ELPRO 115S expansion modules.
