915U-2 Wireless Mesh Networking I/O
and Gateway
Long‑range, scalable, industrial multiple I/O node and gateway
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.
The 915U-2XM is a factory hardware option that
provides 200 MB of extended internal flash memory
specifically for use with the logging soft feature key
option. Soft feature options are available for the 915U‑2
and 915U-2XM, including Modbus TCP and logging.
These are purchased separately and can be enabled as
required via a code provided.
