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 (46.86KHz) 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.
