915U-2 Wireless Mesh Networking IO & Gateway

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 900MHz wireless transceiver, the ELPRO 915U-2 is capable of providing 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, routing node or network gateway. Scalable to thousands of nodes, Gather-ScatterTM and Block Mapping technology offers the 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.
