W&T PCI Express card 2x RS232/422/485, galvanically isolated, 120×120 mm

This PCIe card gives you two flexible RS232/422/485 ports with galvanic isolation up to 1 kV, keeping your equipment safe from voltage differences.⁠‌‌‌‍‌‌‌‌‍‌‍‍‍‌‌‌‍‍‍‍‌‌‌‍‌‌‍‌‍‍‍‌‌‌‌‍‌‍‍‍⁠ Ideal for industrial applications where reliable serial communication is essential.⁠‌‌‌‍‌‌‌‌‍‌‍‍‍‌‌‌‍‍‍‍‌‌‌‍‌‌‍‌‍‍‍‌‌‌‌‍‌‍‍‍⁠

When do you need serial communication?
You use this PCI Express card when you need to connect modern computers to industrial equipment, measuring instruments or older systems that still work with serial RS232, RS422 or RS485 communication. Many professional devices in production environments, laboratories and technical installations still rely on these reliable communication standards.

Why choose a dual interface?
With 2 serial ports on one card, you can connect multiple devices at the same time without needing additional expansion cards. This saves valuable PCIe slots in your computer and keeps your system layout compact. The card supports three different serial standards, giving you flexibility in the choice of connected equipment.

Safety through galvanic isolation
The galvanic isolation, with an isolation voltage of 1 kV DC, protects your computer system against voltage spikes and interference that can enter via the serial connections. This protection is essential in industrial environments where electrical interference and differing earth potentials can cause problems.

Compatibility and dimensions
The card uses a standard PCIe 1.1 x1 connector and fits in almost any modern computer with a free PCIe slot. With dimensions of 120×120 mm, this is a full-height card that requires sufficient space in your computer case. Before installation, check that you have enough free space and that your PCIe slot is not blocked by other components.
