Enclosure types for relay couplers
PLUGSERIES
The modular component system repre-
sents a new generation of pluggable relay
couplers. The key element is an innova-
tive relay base designated PXS (screw
clamp) or PXZ (tension clamp). Both
products reflect the functionality of relays
and terminals, and experience gained
from their commercial use. PLUGRELAY
is the ideal connection system between
the relay and the application.
Modular principle
The new PLUGSERIES is extremely easy
to handle. Commercially available relays
are simply plugged in, retaining clips pro-
vide a firm hold, and LED displays with a
freewheel diode can be plugged in.
•Relays simply plugged in: suitable for
miniature circuit of both standard and
RT designs
•Independent connection technology:
screw connection or tension spring
technology, nominal cross-sectional
area 0.5 … 2.5 mm2
•Robust design of the retaining clip
•One or two change-over contacts;
max. switching current 16 A
•Minimum wiring workload thanks to
ZQV 2.5N pluggable cross-connectors
•Modular system makes for easy han-
dling:
–Relay base, LED display, retaining
hook and relay
–Clips on to TS 35
–Marking with WS tabs on retaining
hook
•Pluggable LED with freewheel diode.
MICROSERIES
Relay and optocoupler versions in the
MICROSERIES are used in industrial
automation applications for separating
and coupling digital input and output sig-
nals. The compact design makes them
perfectly suited for use in sub-distributors
or switch cabinets. With its compact
shape, MICROSERIES combines the
functions of the classical coupling level
with the terminal level.
•Slot-in width 6.1 mm
•Pluggable cross-connection for four
input and output potentials
•Tried and tested ZQV 4N
cross-connection system
•Wide range of input voltage
from 5 .. 230 V
•LED status display, reverse polarity
protection diode, recovery diode
•Enclosure material WEMID (com-
bustibility V0 acc. to UL 94)
•Innovative holding and ejecting
mechanism
•Marking surface to take standard
marking WS 12/6
CE marking
Weidmüller's relay couplers carry the CE
mark and comply with the requirements
laid down by EN 50 081 part 1 and
EN 50 082 part 2. They can be used in
both in a wide range of applications and
industries
Suitable ESD measures must be taken
during installation. Overvoltage protection
must be provided for long leads as pro-
tection from lightning.
WAVESERIES
Innovative electronic components require
an enclosure or housing which reflects
their specific functions. It must allow for
adjusting and control functions and sup-
port technical requirements, such as heat
dissipation or electromagnetic compatibili-
ty. A compact design saves space in the
switch cabinet and reduces assembly
costs. Ergonomic design is increasingly
important for top quality relay coupler
interfaces.
The WAVEBOX fulfils all these criteria,
with outstanding features including:
•Assembly without tools
•Pluggable circuit board
•ZQV 2.5V pluggable cross-connector
•Hinged transparent cover
•Marking with WS tabs
•Clips onto TS 35
Connection systems
The user can choose between BLZ screw plug-in
connectors and BLZF tension clamp plug-in sys-
tems, up to 2.5 mm2and finely stranded, for the
greatest possible flexibility when wiring up the cir-
cuits.
Printed circuit board
If the lateral locking hook is squeezed on the head
end, it can be pulled out of the enclosure together
with the connection level and the circuit board.
The circuit board can only be pulled out without
current voltage.
Cross-connector
The ZQV 2.5 N/2 cross-connectors can be used
to connect rows of Wavebox housings in the lower
part of the enclosure. The cross-connector can
take up to 8 A of current. It can be used for bridg-
ing the supply voltage from one electronic module
to another. The voltage at the cross-connector
must not exceed 50 V.
Ventilation slits
Diagonal ventilation slits ventilate the lower parts
of the enclosures and keep temperatures moder-
ate.
