Fault
Pins
7026TX switches have Fault pins that can be used for an alarm contact. An alarm contact is normally open and the
relay closes when a fault condition occurs. 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. The Fault pins are located on the back and have a current carrying capacity of 1A
at 24VDC.
