915U-D Wireless Serial Modem
RS-232/RS-485 serial data networking
Description
The ELPRO 915U-D Wireless Serial Modem is an RS‑232 or RS‑485
data modem that enables cost effective, two-way communications
between serial devices such as PLCs, RTUs, and other industrial
machinery to host monitoring and control systems. Designed with
a long range, license-free 900‑MHz or 2.4‑GHz wireless transceiver,
the ELPRO 915U-D delivers high performance in a compact DIN rail
or panel mount form factor ideally suited for integrated industrial
applications.
Offering scalability from simple to complex deployments, the 915U‑D
couples data rates up to 500 kbps, with low latency performance
ideal for demanding Modbus® or PROFIBUS® applications. Reliability
is maximized through interference-immune frequency hopping
spread spectrum technology, while security is assured via data
encryption to the AES 256-bit standard.
