2-level protection for analogue and binary signals

The VARITECTOR SPC features a pluggable arrester which can be easily replaced or tested without any re-wiring. The V-TEST testing device enables an easy observance of maintenance intervals. The simple snap-on VSPC BASE allows for convenient mounting while simultaneously establishing a PE contact via the mounting rail. Featuring both, simple operation and high packaging density, the VSPC provides high-quality surge protection for all I&C signals. A coloured voltage marking allows maintenance staff to quickly identify the unit in the cabinet.
This product line also features a complete range of accessories, such as the V-GROUND for earthing all sensor signals or the V-TEST connector for circuit measurements. A VSPC Locking Clip also fixes the pluggable arrester on the base to withstand even extreme loads.
The VSPC R monitoring modules have an integrated message function which is monitored and controlled via the VSPC CONTROL UNIT.
The base element with plugged-in arrester has a total height of 69 mm.

Product group overview

	Surge protection for binary signals and EX ia signals Binary signals with signal contact Binary signals without alert contact, also for EX ia applications	Binary signal (SL – Symmetrical Load) protection includes the following signals: Switching signals with and without a common reference potential e.g. 5 V – 24V – 60 V Two-conductor systems usually involve a common reference potential of binary sensors, actuators and indicators such as limit switches, buttons, position sensors, photoelectric barriers, contactors, solenoid valves, indicator lamps, etc. Pluggable arrester, for interruption-free and impedance-neutral plug-in and pull-out Can be tested with the V-TEST testing device Version with floating-earth PE connection used to avoid interference currents resulting from differences in potential For use in compliance with the IEC 62305 and IEC 61643-22 installation standards (D1, C1, C2 and C3) Integrated PE foot safely discharges up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to the PE Colour coding of the voltage levels for fast identification on the panel Safety function through coding elements for different voltage levels
