Universal Transient Barrier, Dual Pair



  • Compact design universal transient barrier provides protection of low-voltage circuits and transducers
  • Separate plug and base design allows hot swappable module replacement
  • Multi-stage protection and fine over-voltage protection helps ensure lowest residual surge voltages reach sensitive equipment
  • Common-mode and differential-mode protection protects against both possible surge conditions
  • Surge rating to 20 kA 8/20 μs is ideal for exposed wiring
  • Allows for protection of 25 analog signals or 50 digital signals per linear foot (0,3 m) of DIN rail space
