905U-E Wireless Ethernet Modem Long‑range wireless Ethernet for reliable industrial connectivity Description The ELPRO 905U-E Wireless Ethernet Modem is a robust, licensefree wireless transceiver capable of long‑range communications to 20 miles (32 km). Operating at 900 MHz and up to 1W, the 802.11 standards-based ELPRO 905U-E provides reliable and secure two‑way wireless communications in complex applications connecting PLCs, DCS and SCADA systems, data loggers, or field instruments in challenging 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 905U-E offers node‑to‑node, node–to–multi‑node, and repeater functionality for scalability, with additional I/O expansion delivered through the use of ELPRO 115S expansion modules. Security measures using MAC address/IP filtering and encryption to 128-bit AES provide increased reliability. 902–928 MHz frequency and up to 1W RF power (subbands configurable) FHSS to 200 kbps data throughput Bridge/router, access point client–configurable Serial client/server/multicast Modbus® TCP to RTU gateway/ Modbus Point‑to‑point or multipoint functionality, with simultaneous use of RJ‑45, RS‑232/RS‑485 ports 10/100Base‑T IEEE 802.3 Ethernet, RJ‑45 connector Spanning tree (self-healing) support Over-the-air network diagnostics and configuration On-board discrete I/O channel for failure status Data logger communications Serial and Ethernet communications SCADA networks Water/wastewater systems
