Transmitter Surge Protection

The TP series of surge protection devices provide a level of protection for 2, 3 and 4 wire field-mounted transmitters from induced surges and transient voltages, without involving any additional wiring, conduit modifications or other expensive extras.  The TP is mounted easily and directly into any unused conduit entry on the transmitter case and flying leads are connected to the terminal block and the internal earth stud. The TPs operate without in any way affecting normal operation - passing ac or dc signals without attenuation while diverting surge currents safely to earth and clamping output voltages to specific levels.

  • Approved Intrinsically safe, flameproof and Fieldbus variants
  • Parallel connection avoids resistance into loop
  • Low impedance series connection avoids signal degradation
  • 10 Year “No Fuss” Warranty
