DA fault information output
When the DA is working properly, the output voltage is VCC
(12V-24V).
When the DA faults, is protected, or undergoes self-testing,
the output voltage is GND (0V).

VCC (12V-24V, powered by an external device)
8
Self-test port
When the DA output voltage is VCC (12V-24V), the DA is
being self-tested.
When the DA has no input voltage, the DA is working
normally.
