Low Profile PCI card 1x 20mA, 1kV isolated

  • Low Profile PCI card for serial communication, 1x 20mA

An additional TTY port for compact PCs

The 13410 PC Card adds a 20mA port with galvanic isolation to your PC. The additional TTL ports allow any three non-isolated serial ports to be implemented.



  • 1x 20mA interface
  • 3x serial TTL interfaces without galvanic isolation
    • usable with W&T interface modules as RS232, RS422, RS485 or 20mA interfaces
  • 1x 32-bit PCI bus
    • for 5V PCI systems
  • Galvanic isolation between PC and Port 1
    • Isolation voltage 1kV

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3
  • 5 year guarantee

Worth knowing

"Low Profile" PCI cards have the same electrical properties as their counterparts in standard PCI format. Only the height of the cards is significantly reduced compared with the original size and thus allows the cards to be installed in smaller PCs. An additional slot bracket of normal size is included for installing Low Profile cards in standard housings.

Additional interface modules are connected to the interface card using flat ribbon cable and attached to a slot in the PC case. Both components can be ordered as a separate accessory for Low-Profile housing and for standard housing.
