Exsys EX-42034IS – 4-Port RS-232/422/485 PCI Serial Card with Optical Isolation
The Exsys EX-42034IS is a PCI-interface serial expansion card that adds four independent RS-232, RS-422, and RS-485 communication ports to a desktop PC. Built around the FTDI chip-set, it provides reliable serial connectivity for industrial and embedded applications.
Four independent serial ports support RS-232, RS-422, and RS-485 protocols simultaneously
Optical isolation on all ports protects connected equipment from voltage surges and ground loops
Full-Height PCI form factor ensures stable installation in standard desktop towers
FTDI chip-set delivers broad operating-system compatibility and consistent driver support
Das zeichnet die Exsys EX-42034IS aus
Unlike multi-port adapters that share a single controller, this card dedicates independent hardware to each of the four ports, eliminating bottlenecks in multi-device serial setups. The integrated surge protection and optical isolation make it suitable for environments with electrical noise or unstable power conditions.
Ideal für...
Industrial automation engineers, laboratory technicians, and IT integrators who need to connect multiple serial devices — such as sensors, PLCs, measurement instruments, or legacy equipment — to a modern PC without sacrificing signal integrity or port availability.
Anwendung von Exsys EX-42034IS
Install the card in any available PCI slot on a desktop motherboard. Connect serial devices using standard DB-9 or terminal-block cables. The card is immediately recognised by modern operating systems with built-in FTDI drivers, requiring no additional configuration for basic serial communication.
Exsys is a Swiss manufacturer specialising in interface and connectivity cards for industrial and embedded computing. The brand focuses on serial, parallel, and fieldbus expansion solutions, primarily for the Swiss and European industrial market. Products are distributed through Alltron and are known for robust build quality and straightforward driver support.
It adds four isolated serial ports (RS-232, RS-422, RS-485) to a PC via a PCI slot, enabling communication with industrial devices, sensors, PLCs, and legacy equipment.
The FTDI chip-set provides native driver support for Windows, Linux, and macOS. No additional drivers are required for standard serial communication on modern operating systems.
The card uses a Full-Height PCI form factor and is installed in any standard PCI expansion slot on a desktop motherboard. No cables or external power are needed.
