Example calculation for space requirements
The space requirements for a u-remote station with n mod-
ules is calculated as follows:
Height: 120mm + 2 x 40mm (distances at top and bottom)
=200mm
Width: 8mm (end bracket) + 52mm (bus coupler) +
nx11.5mm (nmodules) + 11.5mm (end plate and
end bracket) + 2x20mm (distances to the sides)
=111.5 + nx11.5mm
For vertical installation interchange height and width. When
calculating the width, 4.5mm for the must be added for the
end bracket MEW35/1.
Installation sequence
A u-remote station may only be installed in this sequence
(starting from the left/bottom):
– End bracket
– Bus coupler
– Up to 64 active modules
– End plate and end bracket
If the station has already been congured, please proceed to
the corresponding installation drawing. If you are conguring
the station yourself, please observe the following instruc-
tions:
– Observe the maximum current carrying capacity (see sec-
tion 4.5)!
– Furthermore, the modules may be arranged in any
sequence. In order to configure the station as clearly as
possible, we recommend arranging the modules accord-
ing to their function.
ArrangementofSILmodules
A PF-O-xDI-SIL module can be positioned anywhere in the u-
remote-station. All of the following output modules up to the
next PF-O module are safely disconnected (safety segment).
Multiple PF-O-SIL modules / safety segments can be set up
in a single station.
When using u-remote PF-O-xDI-SIL modules,
please also observe the Modules for Func-
tional Safety Manual.
The manual is available to download from the
Weidmüller website.
Preparationandtherequiredtool
The DIN rail must already be installed. To mechanically install
the u-remote station, you will need a 3-mm screwdriver.
▶ Lay out the modules in the intended sequence.
▶ Check whether the DIN rail feet can be moved on both
end brackets. If necessary, loosen the mounting screw
until the DIN rail feet can be moved freely.
▶ If not done yet, fit an earth terminal to the DIN rail.
