Caution and warning：
Caution and Warning
This product should be connected to 220VAC power supply. Please ensure that the power
switch controller is off when plugging in/out the power to prevent against electric shock.
Please read the manual carefully in advance and strictly follow the instructions when operating
the product.
In case of any abnormal situation, please contact us and never disassemble the product by
yourself.
Please make sure good ground for the controller to avoid electric shock.
Do not stare directly into the light given out from the LED since it do harm to your eyes. If a

1.5 Function description
1.5.1 Automatically/Manually checking/setting the maximum current
This feature is enabled by software only. By default the controller will automatically adjust the controller to light
sources with current 10mA-1A and voltage 24V. This feature can be overridden by software.
1.5.2 General/ Highlight trigger mode
The controller can enter the two modes by turning the working mode switches accordingly (For general trigger mode
switch 1 “OFF”, switch 2 “ON”while for highlight trigger mode, both switch 1 and switch 2 are “OFF”). Set the trigger
delay through adjusting the encoder or software. The range of the adjustable intensity is 0-255. Optocoupler isolation is built
in. For voltage 0-4V, the optocoupler isolation is not conductive and it becomes conductive when the voltage is within 7 -24V.
For default, it is positive edge triggered.

Note：(1) DPA1024E-4 controller can only connect 24V light source.
(2) The maximum current is 1A for single channel and 2.2A for 4 channels.
(3) When manually setting the maximum output current, never connect the controller to the light source with
current lower than the maximum output current. Otherwise, it may damage the light source because of current
mismatch.
(4) Automatically checks for load current once mode: When turning to this mode, the controller will recheck the
load maximum current once.

3、Operation Instructions
3.1 Wiring diagram
Figure 6: Wiring diagram
Step1: Connect the light source to controller (See Fig. 6).
Step2: If the external trigger control is necessary, connect the external trigger source to the controller (See Sect. 3.4).
Step3: Connect power source (AC100-240V) and turn on the power source. If the digital LED displays channel index then
the power is on.
If one needs to adjust the intensity through software, please connect the controller with power off to PC via RS232 or
Ethernet. Run our Demo program or one’s own program (i.e. SDK also available). The parameters for channels can still be
overridden manually via front panel while communicating through serial port or Ethernet (i.e., both host computer and the
controller can be individually adjusted). There is no need to switch the working mode. For the introduction of our Demo
program, please refer to Sect. 4 –“software operation instruction”and Sect.6 –“program manual”.
3.2 Turn on light source
step1: Turn off the controller.
step2: Connect the light source.

3.3 Setting intensity
1、manually setting: Turn both the switch 1 and switch 2 on the front panel to “ON”position to enter the general lighting
mode. Push the encoder. The first digit of the LED will blink. Now one can choose the channel(s). Clock-wise turning the
encoder will increase the index of the channel whereas counter clock-wise turning will decrease the index. The remaining
digits indicate the intensity level (0-255) in decimal form (i.e., for the highest intensity, set the 2nd digit= 2, the 3rd digit= 5,
the 4th digit=5). Push the encoder again to store the value and the LED will stop blinking. Repeat above steps for the
remaining channels.
2、setting via software: See Sect.4 - “software operation instruction”
3.4 External trigger
There are 4 trigger interfaces. COM is the common external trigger negative input signal and TRIG 1、2、3、4 is the
external trigger positive input. Optocoupler isolation is built in. For voltage 0-4V, the optocoupler isolation is not conductive
and it becomes conductive when the voltage is within 7 -24V. For default, it is positive edge triggered.
The controller can enter general/highlight trigger mode by turning the working mode switches accordingly (For general
trigger mode switch 1 “OFF”, switch 2 “ON”while for highlight trigger mode, both switch 1 and switch 2 are “OFF”). The
trigger delay (1-999ms for general trigger mode/ 0.01-5.00ms for highlight trigger mode) can be adjusted through encoder or
software.A decimal point will appear under highlight trigger mode where maximum value will not exceed 5.00.
