2.5  Failsafe Alarm Relay Wiring and Specifications 
The “Failsafe” output relay is provided to signal critical error conditions that may 
occur on RS2000 series products. The contacts are energized upon power-up of 
the unit and remain energized unless a critical error occurs. The proper relay 
connections are shown in Figure 22. Control of the output is user-selectable and 
can be programmed via the Rugged Operating System (ROS®). One common 
application for this output is to signal an alarm if a power failure or removal of 
control power occurs.
