The ELPRO 905U-X series is a license free spread spectrum radio with multi I/O capabilities.  The operate at 900 mHz and utilize the maximum FCC power level of 1 watt.

Typical Applications: 

Wireless “junction-box” in a process plant to connect a large number of I/O points to other parts of the plant and to the plant control-center.

Simple RTU in a SCADA system, connecting I/O points in pump stations, sub-stations, pipeline regulator stations etc.

Machine-2-machine wireless connectivity in factories.

Features:

• Monitoring and control by wireless or twisted-pair wire
• Sensor signals connected at one module (input signals) are transmitted to another module where the signals are recreated as output signals, or passed via serial or Ethernet data bus to a host device such as a PLC or SCADA system.
• Short distance and long distance applications
• Four I/O versions available
• I/O expansion via RS485 multi-drop serial to I/O modules.
