Common load terminal

B20 plug-in jumpers for
the control end
All plug-in jumpers are insulated. The
plug-in jumpers at the drive end (coil) can
be split manually to the required length,
thus enabling the creation of any required
interface groups.
The jumpers are available in the colours
grey, blue and red. .
Options:
Colours used by RELECO in the relays'
test buttons:
- Blue for DC circuits
- Red for AC circuits
In combination with I/O sockets and
the plug-in jumpers, the IRC relay
series permits low-cost, clearly
arranged and reliable realisation of
interface circuits for the input and
output ends of PLC and control sys-
tems.
S10-M and S12 sockets with one and
two contacts, with inputs in series and
identical arrangement of the contacts.
Identical order of coil and contacts on
both sockets.

Each element connects point 6 of the first
socket to point 5 of the next one, always
leaving free the point 5 of the first socket
and the point 6 of the last one, to con-
nect the common polarity cable.
V40, V10
Power bridge bars for sockets
S10-M and S12
V40 bridges join four similar points in four
aside adjacent sockets. They can join up
either among themselves or to V10 units,
to bridge an unlimited number of sockets
S10-M and S12 in any combination.
V10 bridges are units to connect a single
socket to the next one, so you bridge less
or more than 4 sockets.
Made of copper with a current capacity
of 40 A.

Jumper connection on S1O-M and
S12 sockets
The S10-M and S12 sockets and the
new connection jumpers B20, V10 and
V40 enable easy and fast wiring of rows
of relays. The jumpers can be used in a
mixed configuration of S10-M and S12
sockets.
Different jumper colours allow clear
identification. This results in fewer errors,
lower assembly costs and easier inspec-
tion and maintenance work. Available in
grey (standard), red (AC) and blue (DC),
in conformity with the colour coding used
by RELECO for test buttons for relay
identification.
Attention needs to be paid only to the
total current. At higher currents and also
for safety reasons, a current supply at the
start and end of a jumpered connection is
recommended.
V40 plug-in jumpers for the power end
Contacts can be linked to the power ends
with the aid of these jumpers. Normally,
these are the changeover contacts, termi-
nal 11 or 21. The jumpers can also be used
to jumper NC or NO plug-in terminals. V40
jumpers link four identical contacts of four
neighbouring sockets. They can either be
linked to one another or to V10 jumpers to
jumper a number of sockets in any combi-
nation.
B20 plug-in jumpers for the control
endThe sockets S10-M and S12 are
accessible via the plug-in terminals 5
and 6 for A2 (internal connection). Each
element links terminal 6 of the first socket
to 5 of the next socket, and 5 of the first
socket and 6 of the last socket are always
left free to connect the cable. The jum-
per B20 consists of four coherent parts,
which can be separated, however.
V10 plug-in jumpers for the power
end
V10 jumpers can be used to link
individual sockets to one another in
groups. A combination of V40 and
V10 jumpers is possible, depending
on the number of sockets.

IRC series/CSS
Semiconductor relays as an interface to PLC and control systems
AC switches
The CSS-AZ version switches synchro-
nously, i.e. it switches during the passa-
ge through zero. The CSS-AC version
switches asynchronously, i.e. the semi-
conductor switch switches through, inde-
pendently of the phase, at the moment of
detected triggering.
DC applications with mixed components
Input
Application
The CSS semiconductor switches have
a useful life that is practically unlimited in
terms of switching cycles. They operate
without bounce and permit a high swit-
ching frequency
Drive
All versions feature an electrically isolated
input for 5 to 32 V DC. The inputs are
characterised by a minimum delay with a
simultaneously high interference immu nity.
DC semiconductor switches
There are two versions with identical per-
formance data.
The CSS-DCN version has the common
negative terminal 2, and the load is con-
nected to terminal 1. The CSS-DCP has
the common positive terminal at terminal
2. The load is connected to terminal 1.
This corresponds to an NPN or PNP
switch.
