DEMO & SDK.zip

Model No.

Product Features

1. 256 intensity levels

2. 100Mb Ethernet interface

3. RS232 interface

4. Width of the trigger pulse adjustable

5. Very compact housing for easy installation via screws or DIN rail mounting

6. Automatic detection for the rated current of lights,  also can be set manually

10. Trigger signal input: connect an external signal source (e.g. a camera trigger signal) for synchronized strobing of the illumination device.

Device Overview





100 Mb Ethernet port

Ethernet communication interface with the PC


Serial port, female

RS232 communication interface with the PC


DC voltage input port

For 20 - 24 V DC power input


Light port

In total, four lights can be controlled individually


Trigger connector

For connection with an external trigger source such as a PLC,

sensor or camera; output pulse width can be adjusted

Connection Setup

Step 1: Refer to drawing above to connect the light with the controller.

Step 2: For external triggering, connect the external trigger source with the trigger port.

Step 3: Connect the controller with 20 - 24 V DC input. If the intensity of the light shall be controlled via PC, 

           you need to connect the PC with an RS232 cable or Ethernet cable before the controller is switched on.

           Use the provided software or your own application to communicate with the controller. 

           You can adjust the settings via the PC or manually.

Parameter Descripition




Input voltage

20 - 24 V DC

Automatic detection for the 

rated current of lights

For 10mA-0.5A 24V Light

Set via the DEMO software

Max. output current


Set manually or via DEMO software

Short circuit protection


Protection shuts down the related channel, only afterthe fault

removed and restarting the controller can be re-activated

Over current protection


When the current is over 10% of set value the related channel is 

shut down. Channel is reactivated after its restart

Trigger port and setup

This controller series support four trigger modes: real-time positive trigger, real-time negative trigger, rising edge trigger, falling edge trigger. 

There are 4 trigger channels: 4 connectors for Trigger +, and "COM" is the common interface of Trigger -.

The high voltage level (input voltage range is 5V to 24V) and low voltage level (input voltage range is 0V-2V) is separated by the dual optocoupler inside. 

The default trigger mode is rising edge trigger.

Normal trigger mode

Set the controller in normal trigger mode via software.

Intensity levels can be set from 0 to 255; the width of trigger pulse can be set from 1 to 999 ms via DEMO software.

High-intensity trigger mode

Set the controller in high intensity trigger mode via DEMO software.

Output current is 1A per channel. The trigger width of trigger pulse can be set from 0.01 to 5.00 ms via DEMO software.

Sequence diagram


T1 is the trigger delay time, T2 is the width of the trigger pulse.

Normal trigger mode: T1≤80 μs; T2 can be set from 1 to 999 ms.

High intensity trigger mode: T1≤80 μs; T2 can be set from 0.01 to 5.00 ms.
