Data sheet:

Serial PCI base board, 1kV isolated

  • Serial PCI base board, 1kV isolated

Four additional serial ports for stationary PCs

The 13011 PCI Baseboard together with W&T interface modules adds two isolated and two non-isolated serial ports to your PC. The respective interface type can be freely selected by using the appropriate interface module. This makes it possible to equip your PC with different interfaces without having to use multiple cards.



  • 2x serial TTL interfaces with galvanic isolation
  • 2x serial TTL interfaces without galvanic isolation
  • 1x 32-bit PCI bus
    • for 5V PCI systems
    • Cards for 3.3V PCI systems on request
  • Galvanic isolation between PC, Port 1 and Port 2
    • Isolation voltage 1kV

Worth knowing

There are many cases where it is necessary to equip the ports of an interface card with different port models. It may for example be necessary to use COM1 as a 20mA programming interface for a PLC, as the software used only supports this port, while COM2 is connected to an RS232 terminal device.

For such requirements, W&T provides a very smart solution without any need for additional external hardware. The module concept of the serial W&T PC cards allow you to freely select the interface model, as the PC card mainboard is equipped with pluggable modules that convert the internal TTL signals into interface signals.

The combined interface cards are supplied fully configured according to your specifications and are ready for installation. You can change a built-in port at any time by simply replacing the interface module.
