VARITECTOR SPC
Pluggable lightning and surge protection for measurement and control circuits
Pluggable lightning and surge protection for 2 analogue signals or
4 binary signals in measurement/control circuits – with integrated error
detection and alert functions in only 17.8 mm width.
Our pluggable VARITECTOR SPC surge protection is characterised by highest
protective functions with compact dimensions. The arrestor of the modules can
be removed, measured or exchanged during running operation impedance-neutral
– without interrupting the measuring circuit. These features make this product
the ideal secure protection mechanism for interfaces within instrumentation and
control circuits.
Maintenance intervals are simplied by the V-TEST test unit, which is used for
testing the function of the VARITECTOR SPC. This test method satises the
requirements of standard IEC 62305.
With the VARITECTOR SPC R modules, error detection and error messages are
realised by internal monitoring. The green LED indicates the active protective
function. The red LED indicates a fault condition. This information is transmitted
to the V-Control evaluation unit. From there, the information can be sent across
to e.g. a controller.
Due to the impedance-neutral removing of the arrestor, the VARITECTOR SPC
modules can be used instead of terminals. For four binary signals or
two analogue signals, just 17.8 mm of space on the mounting rail is used.
By simply snapping onto a grounded mounting rail, time savings are also
ensured when connecting. A colour code identies the various voltage
levels for all VARITECTOR SPC modules. This simplies maintenance
work during operation. The EMC set offers additional convenience for
connecting shielded cables. All VARITECTOR products comply with the
latest IEC 61643-21requirement for a new overstress mode.
