Balanced positive input of
CH2

Balanced negative input of
CH2
3
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).
4
Balanced positive input of
CH1
5
Balanced negative input of
CH1
6
GND (0V)
7
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.

Balanced positive input of
CH4
10
Balanced negative input of
CH4

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).
