Push-button interface


The push-button interface is used for connecting potential-free N.O. push buttons or NPN transistor outputs to the Niko Home Control installation. The interface converts the switching impulse of the push buttons into a Niko Home Control bus command.

Depending on the variant, you can connect one to four (550-20000), or one or two (550-20025) push buttons or NPN transistor outputs.

Each input contact of the push button interface with LEDs (500-20025) has a feedback LED, that can be used as a control or orientation light.

Within the programming software, each action button connected to a circuit wire of the push-button interface can be assigned to any kind of basic action or routine created.



4 input contacts

no feedback LEDS

2 input contacts

2 feedback LEDs (1 per input contact)
