The RT 800 series provides control of LED lighting for machine vision applications and includes the power regulation, intensity control, timing and triggering functions required for machine vision systems.The RT 800 series also incorporates two Gardasoft innovations - SafePower® and SafeSense® technologies

What advantages does SafePower provide?
SafePower allows much greater flexibility in selection of the DC power supply used and works automatically without configuration or other user input. No heat sinking is required and the output voltage is not limited to the supply voltage. Installation and implementation are much simpler as there is no need to mount the controller onto a heat sink as SafePower automatically minimizes the heat generated for continuous, pulsed and switched operation.

What advantages does SafeSense provide?
Using SafeSense technology, allows the user to overdriveLED lights while protecting the them from damage by ensuring that the high current pulses are regulated in terms of pulse width timing and frequency, obtaining the maximum light possible for the application.

Driving the LEDs with a constant current source allows for very precise overdriving and SafeSense ensures that the pulse width and duty cycle are kept within safe working limits. The end result is that much more light is gained. SafePower® now allows the user to overdrive the lights without having to increase the input power supply voltage, making implementation and system integration more simple.

In addition, SafePower removes the restriction on the output voltage being less than the input voltage and will step-up the voltage as needed to drive or overdrive the lighting, up to a limit of 48V.

Output channels
The RT800 controller range offers eight output channels which are all independently controlled. Each of the eight output channels can be individually configured to output continuously; or to output pulses based on an external trigger signal or internal timer. These controllers allow pulse width control down to 1µS resolution.

Software
The RT820 / RT860 models can be quickly configured using free, downloadable software. For Ethernet enabled RT820 range, access to the controller is via internet browser by using the IP address for the controller in a web browser to gain full access to all of the parameters.

If a third-party software package is preferred, the RT800 range has a simple command set allowing easy communication.

As with all Gardasoft products, all the settings are stored in non-volatile memory, and it will retain these settings even when the Ethernet connection is disconnected.

Special function of the RT820
Leveraging the advantages of Ethernet technology (fast, long-distance and standardised), the RT820 acts as a miniature web server and can be controlled by image processing software on a remote PC . The web browser can be used to access the RT820's internal web pages allowing status to be viewed and parameters to be changed.
