Critical Alarm Relay
The Critical Alarm output relay signals critical error conditions that may occur on the RuggedBackbone™
RX5000. The contacts are energized upon power-up of the unit and remain energized unless a critical alarm
condition is detected. Relay connections are shown in the
Critical Alarm Relay Connection
diagram. Control of
the relay output can be configured via the ROX user interface.
A common application for this output is to signal an alarm in case of a power failure.
