D-sub dataline surge protector

DD9-24V
Part Number 6147
DD9-24V
  • D-Sub surge protector
  • For RS232, RS485 communication lines
  • 9-pin connector
  • Fast and easy installation
  • Secondary protection

DD9ESD surge protector are designed to protect sensitive equipment linked to datalines equipped with D-sub connectors, as RS232, RS422 and RS485lines. They are equipped with D-sub connectors for fast and easy maintenance. In order to comply with the line configuration, all the wires are transmitted and protected.
