Section 2.5
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 RS920W.
To connect the failsafe alarm relay, do the following:
1. Insert the failsafe alarm relay terminal block into the device and tighten the screws.
2. Connect a failsafe device to the terminal block.
