915U-2 Wireless Mesh Networking I/O and Gateway Long range, scalable, industrial multiple I/O node and gateway Features 902–928 MHz frequency hopping spread spectrum (FHSS) up to 1W RF Power 869 MHz wideband up to 500 mW for Europe Self healing IP based wireless mesh networking Multi hop repeater and gateway functionality Gather scatter and block mapping Serial client/server/multicast Modbus TCP to RTU gateway Configurable digital, pulse, and analog I/O to 14 bit resolution 10/100Base T IEEE 802.3 Ethernet Secure 256 bit AES encryption Modbus RTU and TCP support Description The ELPRO 915U 2 Wireless Mesh Networking I/O and Gateway is a multiple I/O node that extends communications to sensors and actuators in local, remote, or difficult to reach locations. Designed with a long range, license free wireless transceiver, the 915U 2 can provide IP based mesh networking across sprawling industrial environments typical of industrial applications. Capable of ad hoc mesh networking, roaming and discovery, as well as deterministic mesh, the 915U 2 can serve as an end node, a routing node, or a network gateway. Scalable to thousands of nodes, its gather scatter and block mapping technology offers efficient utilization of network resources and eases integration into complex monitoring and control systems. Integrated Modbus® server capability allows further I/O expansion through the use of ELPRO 115S expansion modules.
