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.
