5.1.3.3 I/O signal
I/O signal
is used to set five digital output channels to
page
realize alarm functions you need.
In addition, the channels also can work with digital inputs to do
further applications
.
Each digital output channel can flexibly set a source, a trigger
definition, an action and a delay. After tapping an output
channel triggering options will appear. Please refer to the table
,
below for detailed triggering functions.
Source:
Alarm, PSU or digital input channels are available to be selected.
After selection, the corresponding trigger conditions will
appear. For instance: trigger definitions will move to relevant
protection options for the rack powers when alarm is selected.

Trigger definitions:
(1) Alarm: trigger the output channel when one of the supplies
meets alarm conditions, such as OVP, OLP, short circuit or any
of the protections (default).
(2) PSU:
I. PSU ON: trigger the output channel if one of the supplies is
running
II. PSU OFF: trigger the output channel if one of the supplies
is remote off or in alarm conditions.
III. PSU OFF: trigger the output channel if all of the supplies
are disconnect.
(3)DI CH1 CH5(digital input channels): trigger the output
–
channel according to condition of the selected input channel.
Active:
Determine the logic level when outputting. High (high level): 5V;
Low (low level): 0V.
Delay:
Determine how long to delay before outputting when the
trigger condition is met. There are imminently (default),
1Sec …
10Min available
