Inline Terminals Specifically for INTERBUS
20/58 Bosch Rexroth AG | Electric Drives Inline | Application Description
and Controls
Number of devices The maximum number of devices that can be connected to a bus coupler is
determined by the following parameters:
1 The maximum number of devices in INTERBUS is limited to 512.
2 Up to 63 devices can be connected to an Inline bus coupler.
This number includes all the devices after the bus coupler, i.e., the Inline
terminals, as well as the devices that are connected via a branch terminal. The
number of devices on a connected remote bus branch does not affect the
number of Inline station devices.
3 The maximum current that can be supplied by the bus coupler in the logic area
(U
L
) is limited (e.g., R-IBS IL 24 BK-T/U-PAC: 2 A).
4 The current carrying capacity of the potential jumpers is limited. For the limit
values of the individual voltage jumpers, refer to the DOK-CONTRL-
ILSYSINS***-AW..-EN-P application description.
End plate The end plate is supplied as standard with the bus coupler. The end plate
terminates an Inline station and must be placed after the last terminal of the station.
It has no electrical function. It protects the station against ESD pulses and the user
against dangerous contact voltages.
Fuse protection The bus coupler is protected against polarity reversal and surge voltage for the
supplied voltages.
Functional earth ground
connection
The terminal is grounded when it is snapped onto the grounded DIN rail via the FE
spring on the bottom of the terminal. This spring is connected to the FE potential
jumper and to the terminal points for an FE connection (see "Required additional
functional earth grounding" ).
Required additional
functional earth grounding
In addition, connect the bus coupler to functional earth ground via the FE
connection to ensure reliable functional earth grounding of the station even if the
FE spring is dirty or damaged. Connect the terminal points for the FE connection
with a grounded PE terminal (see DOK-CONTRL-ILSYSINS***-AW..-EN-P
application description).
Carrying capacity of the
jumper contacts
The maximum current carrying capacity of the jumper contacts on the side is
specified in the DOK-CONTRL-ILSYSINS***-AW..-EN-P application description.
Observe the specific values of each terminal when configuring an
Inline station.
They are specified in every terminal-specific data sheet.
The permissible number of devices that can be connected depends
on the specific station arrangement. None of the above mentioned
parameters may be exceeded.
