VSPC 4SL 24VAC EX Details

Binary signal (SL – Symmetrical Load) protection includes the following signals:

  • Switching signals with and without a common reference potential , e.g. 5 V...24 V...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 impedanceneutral plug-in and pull-out
  • Can be tested with V-TEST testing device
  • Space-saving design for up to 4 binary signals
  • Version with floating-earth PE connection used to avoid interference currents that result from differences in voltage 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 (8/20μs) and 2.5 kA (10/350 μs) to the PE
  • Colour coding of the voltage levels for fast identification in the cabinet
  • Safety function through coding elements for different voltage levels
