5.3.4 LED strobe control
The SVCam 4I/O concept contains an integrated strobe controller. Its controls are
integrated into the GenICam tree. With LED lights attached to the outputs, this
enables the user to control the light without external devices. Being controlled via
GenICam, any GenICam-compliant 3
rd
party software is able to control the light
as well. Maximum ON-time is 100ms. Depending on the camera model, up to 4
(see specifications) independent channels are supported with a max current of
3A@40ms 1A@40ms. Maximum continuous current is 0.3 A. Despite internal pro-
tections, higher current peaks might be able to damage the camera.

NOTICE To avoid destruction of your LED light or camera, make sure to use the
right dimension of shunt resistor. If not done so, LEDs and/or Camera
might be damaged.
Calculate LED shunt resistors
Shunt resistors are used to limit the LED current. Make sure, neither shunt nor
LED run above specs.
LEDs in continuous mode
Voltage drop al 5 LEDs, 2,2V per LED (see spec. of
LED) 11 V
Max. continuous current (see spec. of LED) 250 mA
Voltage supply 24 V
Voltage drop at resistor (24 V – 11 V) 13 V
Pull up Resistor R =
52 Ω
