8 analogue 10 bit resolution inputs: 0&5 or 10VDC / 20kohm;
8 analogue 8 bit resolution outputs: 0&5V or 10VDC / 47ohm;
8 digital inputs: open collector compatible (connection to GND=0) with on board LED indication;
8 digital open collector outputs (max. 50V/100mA) with on board LED indication;
One 10 bit PWM output: 0 to 100% open collector output (max 100mA / 40V) with on board LED indication;
General response time: 4ms per command;
USB Port: 2.0 and 1.1 compatible (USB cable included);
Power consumption through USB port: approx. 60mA;
Up to 8 cards can be connected to PC;
Power supply through adaptor: PS120512Vdc / 300 mA;
PWM Frequency: 15,6 KHz;
PCB Dimensions: 195 x 142 x 20mm (2.7 " x 5.6" x 0.8");
Minimum system: pentium class CPU with free USB port (1.1 or higher)

Now it's possible to have Velleman k8061 on GNU/Linux thanks to the following projects open source;

k8061; this software contains a port of the Velleman K8061 USB Interface library (just a very simple library to use in different projects, analogous to the k8061.dll) and a command line interface for using the card on a linux system. It is licensed under the GNU GPL version 2;
k8061utils; these utilities provide multi purpose control of up to 8 k8061 USB interface boards including k8061d (daemon), k8061m (memory client), and k8061s (socket client). It is licensed under the GNU GPL version 3.
