UTBDP

Universal Transient Barrier, Dual Pair

The UTB series is designed to provide transient protection for equipment from surges induced onto balanced pair signal lines or low-voltage AC or DC power supplies. The compact series is well suited to applications where panel space is limited, yet provides similar protection performance when compared to the UTB Modular series. They are well suited to the protection of industrial equipment such as PLCs and SCADA systems.

The UTB-DP (dual pair) employs a hybrid, multi-stage clamping circuit to help ensure the best possible protection to sensitive electronic equipment while maintaining a minimum of line interference and insertion losses.

FEATURES

  • 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
