This RTU was designed for a Lift Station using 450MHz radio based SCADA and a backup RACO Alarm Dialer.  The RTU and the Alarm Dialer each have battery backup which provides for redundant path reporting of critical alarms such as High Wetwell Level and Power Fail.

All of our RTU’s are built with surge protection on every wire entering or leaving the enclosure.  As a result, we experience less than 1% failure of expensive electronic devices.
