Available now from Weidmuller , the Varitector SPC is a pluggable surge protection device that provides an optimal foundation for the protection of measurement and control signals in photovoltaic applications.
The Varitector SPC pluggable surge protector offers a high level of protection with compact dimensions. Thanks to the ability to removed or exchanged the arrestor modules during running operation without interrupting the measuring circuit, the product is ideal for protecting instrumentation, control, and automation circuits.
With the Varitector SPC R modules, error detection and error messages are realised by internal monitoring. The green LED indicates the active protective function and the red LED indicates a fault condition. This information is transmitted to the optional V-Control evaluation unit, from which the information can be signalled at a controller, for example.
Due to the impedance-neutral removing of the arrestor, the Varitector SPC modules can be used instead of terminals, saving valuable space in the switching unit. In fact, for four binary signals or two analogue signals, just 17.8mm of space are used. Time can also be saved when connecting by simply snapping onto a grounded mounting rail.
A colour code identifies the various voltage levels for all Varitector SPC modules which simplifies maintenance work during operation.
