HDSP CAN/12

Article number: 56 052
  • Two-stage surge protection of connected CAN bus device.
  • They are installed prior to the protected equipment and at the interface of LPZs 1 – 2 and higher.
  • They increase the EMC level of the connected equipment against switching and atmospheric transients.
  • The connection of the module allows to use the operating range of CAN bus drivers in the range of +/- 12 V (common-mode voltage range).
  • Connecting the module allows the full CAN bus speed of 1 Mb/s to be used.
  • They provide cable shield protection by limiting pulse overvoltage through a built-in 90 V gas discharge tube.
