B1 Repeater
Installation manual
Introduction
The compact PROFIBUS DP Repeater B1 offers an economic alternative and tackles the technological limitations of the existing repeaters. This first-class network component fulfils the electrical, mechanical and diagnostic requirements of the demanding modern industry.
The advanced 12 Mbps core of the B1 is identical to the ProfiHub; it can be cascaded unlimitedly and is equipped with the latest isolated RS 485 interface. The data is constantly monitored for glitches which are digitally filtered out. Every channel has on-board switchable termination and can drive 31 devices.
The removable screw terminals of the PROFIBUS interface are pinned-out in a way that reversal mounting does not impact existing wiring. A DB9 connector is provided for ProfiTrace or other maintenance/engineering tools.
The power supply is redundant which makes it suitable for applications in which high availability is required and consumes relatively low power which helps the environment.
Installation instructions
Location
The B1 can be installed everywhere in a non-hazardous area that complies with IP 20 (DIN 40 050) and the specified temperature range of -20 to +60°Celsius.
Position
The B1 can be installed in every position, but it is recommended to install it with Channel 2 pointing down. In this position it is easier to read the status display and to perform measurements on the DB9 connector.
Mounting and dismounting
The B1 has to be mounted on a 35 mm DIN-rail with a minimum width of 60 mm. Fig. 1 and Fig. 2 illustrate how to mount and dismount the B1 on and from the DIN-rail.
Power supply
Parameters
The power supply has to comply with
the following specifications:
Voltage: 19 to 28 Vdc
Current: Min. 65 mA
Wiring
The leads of both power connectors have
to be wired as follows:
“+” = Positive Voltage
“-“ = 0 V
SH = Earth
Redundancy
Both power connectors are linked 1-on-1 to the internal power supply of the B1. If 1 power supply would fail, the other takes over without delay time. When redundancy is not required, it is sufficient to use 1 power connector. When the B1 is flipped 180° , the connectors can be used without alteration. Fig. 3 illustrates the location of the power supply connectors.
PROFIBUS
Connectors
Each channel has 2 connectors (IN and OUT).
They are both linked 1-on-1 when the termination is OFF.
When a channel of the repeater is NOT the last device on the segment, it doesn’t matter which connector is utilized.
When the termination is ON the OUT connector is NOT connected.
When the B1 is flipped 180° , the wired connectors can be used without alteration.
Pin layout
Pin “A1/2”: Green wire
Pin “B1/2”: Red wire
Pin “SH”: Cable shielding
Termination
Each channel has its own termination which can be switched ON/OFF.
Piggy back connector
The piggy back connector is 1-on-1 with channel 2.
Ground Clip
It is recommended to use the supplied GC-01 ground clip to attach the cable shield to the screw connector, as shown in fig. 4, for easier shield connection and better strain relief.
The Ground Clip GC-01 can be ordered separately per 25pcs with order code: 101-00201B.
