KNX Transceivers onsemi KNX Transceivers are ideal for KNX twisted pair networks (KNX TP1−256). The devices support the connection of actuators, sensors, microcontrollers, switches, or other applications in a building network. They handle the transmission and reception of data on the bus. They generate from the unregulated bus voltage stabilized voltages for their own power needs. They can also power external devices, for example, a microcontroller.
