Siemens N 146/03 – IP Router Secure

The IP router is a rail-mounted device for installation in distributions. The device
uses the KNXnet/IP standard and connects KNX lines to each other via data
networks using the internet protocol (IP). At the same time, this device enables bus
access from a PC or other data processing devices.
The connection to KNX is established using a bus connector terminal (black and
red terminals). The connection to the data network (IP via 10 or 100BaseT
(depending on the switch)) is established using an RJ45 socket.
The IP router also needs operating voltage in order to operate. The IP router can
obtain this operating voltage via the network line using “Power over Ethernet” as
per IEEE 802.3af. Alternatively, the operating voltage can be obtained via the
second terminal block (white-yellow terminals) from an AC/DC 24 V safety extra
low voltage supply or from a bus voltage supply (unchoked voltage, DC 29 V). As
soon as the safety extra low voltage supply is connected to the second terminal
block, operating voltage is drawn from it.
