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

Relay
Relay is used to set four programmable relays to realize alarm
functions you need. In addition, the relays also can work with
digital inputs to do further applications
.
Each relay can flexibly set a source, a trigger definition and a
delay. After setting, click
to write your new parameters.
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 definition:
(1)Alarm: rigger the output channel when one of the supplies
T
meets alarm conditions, such as OVP, OLP, short circuit or
any of the protections (default).
(2)PSU: I. PSU ON: rigger the relay if one of the supplies is
T
running
II. PSU OFF: rigger the relay if one of the supplies is
T
remote off or in alarm conditions.
III. PSU OFF: rigger the relay if all of the supplies are
T
disconnect.
(3)DI CH1 CH5(digital input channels): rigger the relay
–
T
according to condition of the selected input channel.
Delay:
Determine how long to delay before triggering the relay when
the trigger condition is met. There are imminently (default),
1Sec
