NCN51206GEVB: 9600 Baud KNX Transceiver

The NCN5120 Reference Design mimics a switch application suitable for use in KNX twisted pair networks (KNX TP1-256). Only 2 wires are needed for communication and power. It contains the NCN5120 KNX Transceiver which handles the transmission and reception of data on the bus. It will also generate all necessary voltages to power the board and external loads.

The Reference Design contains a microcontroller with debug interface for custom firmware development. Up to 4 external switches can be monitored and up to 4 external loads can be controlled. A voltage between 3.3 V and 21 V is available to drive the external loads. The NCN5120 Reference Design assures safe coupling to and decoupling from the KNX bus. Bus monitoring warns the external microcontroller for loss of power so that critical data can be stored in time.
