Gardasoft Vision Lighting Controllers

LEDs are current driven devices and current control from the LED power supply is essential for precise intensity control. The Gardasoft LED Lighting Controller range offers precise current control (strobe, pulse or continuous control) to ensure stable and repeatable illumination for Machine Vision Lighting and Image recognition systems.

Available in 1, 2, 4, 8 and 16 channel modules, the Gardasoft range of LED Lighting Controllers allows the user to precisely control an LED light module on each channel.

Gardasoft RT / RC Series Pulse Controllers

Each channel is controlled independently, with either continuous output or strobing of the light, with timing control down to 1µS on selected models so fast moving objects can be ‘frozen’ when imaged. Gardasoft’s patented SafeSense™ allows the LEDs to be overdriven safely, protecting the LEDs whilst optimising the amount of light produced. The Gardasoft White Paper on LED Controller technology is a useful reference for the principles of attaining maximum performance for Machine Vision illumination.

For Complicated Applications

The RTCC4 combines all the features of the Gardasoft RT Series with the timing functionality of the CC320. The combination provides a high level of integration in Machine Vision systems – saving complexity, space and costs.

Some applications have fixed speed mechanisms and the time from the trigger to the reject gate is well known; for others, an encoder may be used to determine belt movement. Two types of encoder input are supported – one wire systems which have distance only, and two wire systems having distance and belt direction only.

Taking the functionality of the Gardasoft RTCC4 Timing Controller and integrating this into the RT Series controllers enables precise lighting control combined with the ability to trigger external components such as cameras and reject gates. In addition, inputs can be accepted from encoders or proximity switches that can then be used to trigger the lights or one of the additional digital inputs. The Gardasoft White Paper on LED Controller technology is a useful reference for the principles of attaining maximum performance for Machine Vision illumination.
