2.3.4 Profibus module SK TU2-PBR-KL
•
WAGO terminal block, type 218, 8-pin
• Network termination resistor (220Ω) can be switched in
• SUB-D 9 test connector for production, testing and bus
signal analysis
Wiring should be via 2x M16 cable glands. The Profibus option
is supplied with two M16 dummy cable glands. There are
therefore no plug connection contacts outside of the housing.
With this option, normal and coloured 8-pin WAGO series
terminal blocks, type 218 are used. In combination with the
cover, the high protection class IP55/66 is implemented.
The Bus data cables are in parallel on terminals 3 and 6 (A data, green terminals) as well as 4 and 7
(B data, red terminals). It is therefore very easy to differentiate between incoming and outgoing cables.
An additional 24V supply is not required, the power supply is provided by the frequency inverter.
Strain relief, as well as the shield contact of the Profibus
cables, is via the double shield terminal on the PCB.
For analysis and test purposes, a 9-pin SUB D socket is
available to users for the connection of Profibus analysis tools.

By loosening the two M3 knurled screws, the connection board
of the Profibus option can be removed in order to facilitate
connection of the Profibus cables.
