UTBSP

Universal Transient Barrier, Single Pair

The UTB series is designed to provide transient protection for equipment from surges induced onto balanced pair signal lines. They are well suited to the protection of industrial equipment such as PLCs and SCADA systems. Other uses include the protection of fire and security alarms, industrial monitoring and control equipment. The UTB-SP (single pair) employs a hybrid multistage clamping circuit, to help ensure the best possible protection to sensitive electronic equipment while maintaining a minimum of line interference and insertion loss.

FEATURES

  • Compact design universal transient barrier provides protection of low-voltage circuits and transducers (sensors and actuators)
  • 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
