NT24k Fault Pins
The Fault pins on the back of the NT24k can be used for an alarm contact. The current carrying capacity is
1A at 24VDC. It is normally open and the relay closes when a fault condition occurs, though this can be
reversed via configuration. These pins can be used to connect an external warning device such as a light in
order to provide an external alarm. The conditions for generating a fault condition (closing the relay) can be
configured through software.
