VARITECTOR SPC
VSPC TAZ
VSPC MOV
The VSPC MOV 2CH and TAZ 2CH
offer one-stage protection with a
varistor (MOV) or suppressor diode
(TAZ or TVS) between the current
paths. This makes it possible to protect
a no-voltage (oating) signal circuit.
Two binary signal circuits can also
be protected if terminals 1 and 7 are
assigned to GND / PE. These VSPC
pluggable components are inserted
into the base (VSPC BASE 2/4CH).
The base (VSPC BASE 2/4CH FG) is
used when working with signal circuits
which are not earthed.
24 V
VSPC 1CL PW
VSPC 1CL PW (power and signal
1CL) offers combined protection that is
suitable for the 24 V DC power supply
and the current loops within a device.
This VSPC protects sensors with an
additional 24 V DC.
VSPC RS422/485
The VSPC RS485 is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
located between the current paths. This
VSPC RS485 limits the surge voltage
within two high-frequency signal
circuits. This pluggable component
can be inserted into the base
(VSPC BASE 2CL). The base
(VSPC BASE FG 2CL) is used when
working with signal circuits which are
not earthed.
Monitoring function
The VSPC RS485 R product features
monitoring and alert functions. Even
with the alert function, there are still
two channels available for current
loops in a single housing. The special
VSPC BASE 2CL R and VSPC BASE 2CL
FG R bases transfer the alert function
to a 2-pole screw/plug-in connection in
the bases and to the
VSPC CONTROL UNIT.
Earthing unit and test plug
The earthing unit can be used
during installation to short out the
connected wires to earth. The earthing
unit is swapped out for a VSPC
pluggable component before the
initial commissioning. The test plug
has 2.3-mm sockets. These sockets
can be used by a meter to check the
connected measurement circuit.
Applications
The pluggable INSTA housing was
created in compliance with DIN 43880.
It consists of a lower section
(the VSPC BASE) and a pluggable
component (the VSPC). The VSPC
BASE is made from black PA6.6 V0.
The pluggable component is made
from red PA6.6 V0. The temperature
range is from -40 °C to + 70 °C.
The VSPC series has been tested to
comply with IEC 61643-21 04/2008
and EN 61643-21. Modules were
tested with categories C1, C2 and C3:
with quick-rising edges with up to 300
pulses. Category D1 describes high
power testing (10/350 μs lightning
protection), so that the VSPC can be
used according to IEC 62305-4.
The base and pluggable components
are colour coded according to the
voltage level. This makes installation
easier.
Colour coding
The pluggable components transfer
their coding to the base element when
they are plugged in for the rst time.
The voltage levels are also labelled with
coloured Dekax markers applied to
the VSPC pluggable component. This
gives you a better overview within the
electrical cabinet.
