hager TXB201A Switch actuator for bus system

A minimal KNX setup

EIB KNX IP Interface PoE, with up to 5 tunneling connections

1. a 29V power supply  >= 300mA

2. a KNX choke or 47-Ohm between PS and bus line

3. a KNX sensor (push buttons +  KNX bus coupler)

4. a KNX actuator Some KNX sensors (like wall-mounted push buttons) have status LEDs that can be controlled from the KNX bus. In this case, you do not need a separate actuator. Otherwise have a look on eBay for old binary outputs

5. USB or Ethernet interface: more flexible multiple devices can access it simultaneously
