Weidmüller relay sockets for mounting rails
enable plug-in relays most commonly
used in industry to be mounted; they
make possible installations in which the
control section and power section are per-
fectly separated. The coil terminals and
the connection terminals are located on
opposite sides of the locking socket mod-
ules.
The conductors are connected via screw
terminals; the securing in the terminal is
achieved by a clamping yoke system. This
method has been used by Weidmüller for
many years, and is the only method that
guarantees a reliable connection in indus-
trial applications.
Thanks to their combination foot, these
modules can be mounted onto TS 32, TS
35x7.5, TS 35x15 mounting rails in accor-
dance with European standards EN 50035
and EN 50022.
The connections are marked according to
European Standard EN 50005. The mod-
ules are designed for DC relays (with a
damping diode parallel to the coil, as well
as a protection diode for reverse polarity
protection) and AC relays.
They can be provided with an LED on
request.

The input terminals are doubled, in order
to pick off the poles. Note the following for
DC current operation:

Relay Socket Module for Industry Relays
The contacts available at the output are:
2, 3 or 4 changeover contacts.
The marking of the contacts in the follow-
ing diagram corresponds to European
standard EN 50005.
The standard range of relay socket mod-
ules is divided as follows:
Group 1:
RS 3 (2 changeover contacts)
RS 4, RS 14 (4 changeover contacts)
For relays of the type “international”
Group 2:
RS 6 (2 changeover contacts)
RS 7, 17 (3 changeover cont.)
RS 8, 18 (4 changeover cont.)
RS 9 (2 changeover cont.)
For relays of the type "European".
Relays with 4 changeover contacts (size 2)
can be secured to RS 7, RS 17 and RS 9;
however, only 3 or 2 changeover contacts
are connected to the terminals, which
results in space savings.
Group 3: RS 21 (2 changeover contacts)
For relays with one socket with 8 or 11
pins.
The table on page 87 offers an overview of
the most important manufacturers of
relays in groups 2, 3 and 4. The list is pro-
vided for information purposes only, and
