PSI-REP-PROFIBUS/12MB
1.1
Bit Retiming
PROFIBUS signals with a bit distortion of up to 35% can be
reliably detected using the bit retiming function and are
converted to their original bit form before being transferred
to the next segment. This data processing function means
that a virtually unlimited number of repeaters can be
aligned without an impermissible level of bit distortion.
2
1.2
Bit Oversampling
The bit oversampling function can be used to detect and
filter malfunctions so that they are not transferred to the
next segment.

Applications
Stub line
The PSI-REP-PROFIBUS/12MB repeater can be used to
create network topologies that are ideally adapted to the
relevant application.
The limits set by the PROFIBUS standard, which specifies
the electrical properties of PROFIBUS, are thus extended.
This standard defines the following basic specifications:
1. Maximum of 32 devices per potential segment
2. Only (linear) bus structure permitted
3. Maximum bus cable length 1200 m
4. Maximum branch line length of 5 m without termination
resistor (depending on the transmission speed)
5. Bus cable termination at the start and end of the bus
cable
PROFIBUS 12 MBit/s
100m
100m
Max. 31 devices
= Switch on bus termination resistor
Linear structure
Example Applications for Repeaters
A segment can be created as an active branch, which can
comprise the full bus cable length and a maximum of 31
devices.
Electrical isolation and bus segmentation using repeaters
enables the permissible bus cable length to be multiplied
and the number of devices to be extended to n x 32, since
the total number of devices of the PROFIBUS specification
applies in each potential segment.
The repeater supports higher transmission speeds by
subdividing into shorter segment lengths. For example, a
200 m PROFIBUS system can only be operated at a
transmission speed of 1.5 Mbps. The use of a repeater after
100 m means that 8 times the performance can be
achieved, i.e., 12 Mbps.
Hybrid/network structures, star, and tree structures can be
created using the PSI-REP-PROFIBUS/12MB modular
repeater. A freely selectable installation concept,
independent of the restrictive linear structure, is thus
possible. The repeaters can be extended using
PSI-MOS-PROFIB/FO... fiber optic converters for
PROFIBUS systems.
In addition, the repeaters can be combined and thus
configured to form a modular PROFIBUS hub.

Connection Notes
Only mount and remove devices when the
power supply is disconnected.
8.1
Combined Assembly With a System Power
Supply (Modular Star Coupler)
1.
Connect together the required number of DIN rail
connectors for the connection station. Two DIN rail
connectors are required for each device (see A in
Figure 5). A maximum of ten devices are permitted in a
connection station.
Push the connected DIN rail connectors onto the DIN
rail (B and C).
Place the device onto the DIN rail from above. The
upper holding keyway of the device must be hooked
onto the top edge of the DIN rail (see Figure 6 on
page 9). Make sure that it is aligned correctly with the
DIN rail connectors.
Once the device has been snapped on properly, check
that it is fixed securely on the DIN rail.
Warning
Disregarding this warning may result in
damage to equipment and/or serious personal
injury. Only qualified personnel may start up
and operate this device. According to the
safety instructions in this text, qualified
personnel are persons who are authorized to
start up, to ground, and to mark devices,
systems, and equipment according to the
standards of safety technology. In addition,
these persons must be familiar with all warning
instructions and maintenance measures in this
text.
PSI-REP-PROFIBUS/12MB devices are
designed exclusively for SELV operation
according to IEC 60950/EN 60950/
VDE 0805.
•
Install the device on a 35 mm DIN rail according to
DIN EN 60715. To avoid contact resistance only use
clean, corrosion-free DIN rails. End brackets should be
mounted on both sides of the device to stop the
devices from slipping on the DIN rail (for ordering data
see page 2).

surface.
Once the device has been snapped on properly, check

Removal
Pull the locking latch down using a screwdriver,
needle-nose pliers or similar.
Pull the bottom edge of the module away from the
mounting surface.
Pull the module diagonally upwards away from the DIN
rail.
If removing a complete star distributor, remove the DIN
rail connectors from the DIN rail as well.
102986_02_en
When the devices are operated in a star coupler
configuration, the supply voltage must only be supplied to
the first device in the station. The remaining devices are
supplied via the DIN rail connector. A redundant supply
concept can be created by connecting a second power
supply unit to another device in the configuration.
Using the MINI-SYS-PS-... System Power Supply Unit
As an alternative, the star coupler configuration can also be
supplied using the MINI-SYS-PS 100-240AC/24DC/1.5
power supply unit (Order No. 2866983). It is connected via
two DIN rail connectors.
Usually the system power supply unit is mounted as the first
device in a configuration. A second power supply unit can
be used to create a redundant supply concept.

Wiring the Switch Contact
24 V DC
PSI-REP-PROFIBUS/12MB repeaters are equipped with a
floating switch contact for error diagnostics (connection
terminal blocks 3 and 4 in Figure 3 on page 5). This contact
opens on the relevant device in the event of a transmission
error at port A or port B.
The switch contact is an N/C contact and can be linked to a
local digital input, e.g., on the PLC, to support error
detection.
If devices are combined (in a modular star coupler
configuration), the individual contacts can be linked to
separate input points (Figure 8) or the individual contacts
can be looped to generate a group message (Figure 9).
The maximum load capacity of the relay
contact is 60 V DC/42 V AC, 1 A.

Use shielded twisted pair data cables.
Connect the cable shielding at both ends of
the transmission path.

Use a suitable connector (e.g., SUBCON-PLUSPROFIB..., see page 2) to connect the bus cable to the
D-SUB connection on the repeater.
If the repeater is located at the start or end of an
electrical PROFIBUS segment, activate termination in
the connector.
