HDTNV1/12B

Article number: 56 003/NV
  • Designed for the protection of data and communication lines against longitudinal and transverse surge effects.
  • Pluggable version.
  • No interruption of communication bus when the module is removed.
  • One pair or two pairs lines.
  • Contains both 1st and 2nd stage of protection.
  • The HDTNV*/*C range, in addition, contains a gas discharge tube between the PE and SH (shield) terminals for their galvanic isolation.
  • The inserted series impedance consists of inductors, which allow the nominal current up to 1,5 A permanently flow through the protection. This predetermines the equipment for protection of the power supply line of the system.
  • It can be used for the protection of analog data lines using the current loop 4 to 20 mA.
  • Not suitable for digital data transmission with high transmission speed.
