Product description
Interfaces for connection to the system bus
(XDAC1, XDAC2)
The NK350 network coupler integrated in the
CS351x-D NK Compact System allows connecting
the compact system to the system bus of the 350
system. In this case, the CS351x-D NK Compact
System can only cooperate with a KE350
communication unit that is installed in the BT356
subrack or SB356 system box. You cannot
operate the CS351x-D NK as isolated system.
The NK350 network coupler allows up to 40
tightening channels in up to 16 BT356 subracks,
SB35x system boxes and Compact System
CS351x-D NK to be networked. It is equipped
with an LED display for the illustration of network
conditions. The address of the CS351x-D NK is
set using the hex coding switch.. Additional bus
termination resistors are not required.
The total cable length in the network is limited to
150 m. The maximum cable length between two
network couplers may not exceed 50 m. The
network cable between two network couplers may
consist of no more than four partial segments. A
ring structure is not permissible in the network
configuration.
The D-Sub plugs of the network
cables NKLxx have the protection
class IP40. If several cables are
assembled, the user must ensure the
higher degree of protection that is
possibly required.
If a network cable is created from several partial
segments, distance segments are required at the
connection points.
