DIGITAL OUTPUTS :
8 open collector contacts, to be connected with suitable inputs.
These exits function as ‘dry contact points’: you need an external voltage to control a component such as a LED or a
relay switch.
ANALOGUE OUTPUTS :
2 analogue outputs with an output voltage between 0 and +5V (impedance 1K5).
2 PWM outputs with a pulse width modulation between 0 and 100%.
A fixed PWM frequency (23.43kHz) is used.
REMARK: the analogue outputs and PWM outputs are always activated /deactivated together.
Connection / settings
The demo software makes it easy to experiment. Start by selecting the
address : tick off SK5 and/or SK6 (see address selection).
ATTENTION : Execute these settings before connecting the kit with the
computer or before booting the computer.
Connect the USB cable.
LED LD3 'Power' lights up if the connection has been executed properly.
After startup LD8 (output 8) will flash momentarily to indicate that the circuit works as it should.
Start the program 'K8055_Demo.exe'.
! Next press the 'connect' button to connect the K8055 with the computer.
