IM 153-2 High Feature (for extended temperature range)
Function
Linking of PROFIBUS DP (9.6 Kbps
to 12 Mbps, slave functionality) and
PROFIBUS PA (master functionality)
with support of the "Configuration in
Run" function
The DP/PA link function is only imple-
mented by extending the IM 153-2
High Feature with one or more DP/PA
couplers. Stand-alone operation of
the IM 153-2 High Feature is not pos-
sible.
1 Y coupler, up to 5 DP/PA couplers
or up to 64 slaves can be connected
Isolation from the higher-level DP
master system
Bus connection
• Connection for PROFIBUS DP
9-pin Sub-D plug, contact assign-
ment as described in IEC 61158/
EN 50170, Vol. 2
Connectable lower-level
components
Number of couplers
• DP/PA coupler
Max. 5
• Y coupler

Number of PA devices
on PROFIBUS PA
Max. 64

Voltages, currents, potentials
Supply voltage
24 V DC (20.4 V ... 28.8 V)
Reverse polarity protection
Yes
Voltage failure bridging
20 ms
Galvanic isolation
•
to the higher-level DP master system
Yes
• to the DP/PA coupler or Y coupler
No
Power consumption of modules
(24 V DC)
• In the PA link
Max. 200 mA (at 20.4 V)
• In the Y link
Max. 400 mA (at 20.4 V)
Power loss of the module
• In the PA link
Max. 2.6 W (at 28.8 V)
• In the Y link
Max. 3.6 W (at 28.8 V)
Infeed, mechanical design
4-pin screw terminal, short-circuiting
link between PE and M24;
the short-circuiting link must be
removed for floating operation
(independent of this, the DP interface
is always floating)

Red LED "BF 1"
• Bus error on underlying bus system
Red LED "BF 2"
• Module is active in
redundancy mode
