Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO (Normally Open) contact is
closed when the unit is powered and there are no active alarms. If the device is not powered or if an active alarm
is configured, the relay opens the NO contact and closes the NC (Normally Closed) contact.
NOTE
Control of the failsafe relay output is configurable through ROS. One common application for this relay
is to signal an alarm if a power failure occurs. For more information, refer to the ROS User Guide for
the RUGGEDCOM RSG2300.
The following shows the proper relay connections.
