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 ac-
tive 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 RUGGEDCOM RS400F .
One common application for this relay is to signal an alarm if a power failure occurs.
For more information, refer to the
RUGGEDCOM ROS Configuration Manual
for the
RUGGEDCOM RS400F.
The following shows the proper relay connections.
