Quad Controller

DCS-400E Controller

4 Independent Channels, 1 Output Connector

Includes built-in pre-programmed sequencing.

Provides control for computational imaging, including photometric stereo, extended depth of field, combined bright field + dark field, high dynamic range, and high resolution color.

Ideal for multi-channel lights and multi-light stations. Due to power output constraints, some configurable light lengths may be limited.

Housed within a compact enclosure with DIN rail mounting.

Driven with SignaTech™ for improved safety and easy operation.


Whether you’re looking to create shapes from shading using computational imaging or building a multi-point inspection line, Advanced Illumination’s Quad Controllers are engineered to solve a wide variety of applications.

The DCS-400E provides a total of 4 channels, each capable of firing independently. Built-in pre-programmed sequencing, allows users to progress through pre-determined recipes.  This provides users the ability to automatically time a lighting sequence and output a correlated camera trigger, and to do so through multiple pre-programmed routines.  As an example, by using the DCS’ frame-start signal, it is possible to synchronize a camera exposure to capture each channel as they flash in sequence.

Driven with Ai’s proprietary SignaTech™, the DCS-800E and DCS-400E delivers peak performance while maintaining safe currents for ensured long-term stability.

Both Quad Controllers are housed in a compact enclosure with DIN rail mounting, delivering seamless integration into your existing machine vision system.

*Values shown are based on controller component limitations. Actual limitations will vary depending on the limits set for the connected light head. These limits are determined using Advanced Illumination's proprietary SignaTechTM (Signature Technology) in order to ensure safe peak performance.

** Various light head configurations available, including 1 x 4-channel quadrant (Q1) control or multiple single light heads (Q4) per block.

Multi-light stations are currently limited to the following group of identical light heads.  A future development will allow the Quad Controllers to drive up to eight different configured lights simultaneously.

DF198 - Dark Field Ring Light
DF241 - Small Low Angle Dark Field Ring Light
DF242 - Large Low Angle Dark Field Ring Light
LL174 - High Intensity Bar Light
AL295 - MicroBrite™ Bar Light
AL116 - High Dispersion Wide Bar Light
AL126 - High Dispersion Narrow Bar Light
LL232 - MicroBrite™ Line Light
SL243 - MicroBrite™ Small Spot Light
SL244 - MicroBrite™ Spot Light

Note: due to power output constraints, some configurable light lengths may be limited.
