NI PCI 485I 2 Serial Interface is designed for industrial environments where stable and interference-free serial communication is essential.
In many industrial systems, communication issues don’t show up immediately — they appear when noise, interference, or unstable signals start affecting performance. That’s exactly where a reliable serial interface card like the NI PCI-485I/2 becomes important.
This 2-channel isolated PCI serial interface is built for RS-422 and RS-485 communication, two standards that are still widely used in automation, monitoring, and data acquisition environments. Once installed in a compatible PCI slot, it allows stable communication between multiple connected devices without the signal disruptions that often occur in electrically noisy environments.
What makes this model practical for industrial use is its isolation design. In real factory conditions — where motors, drives, and heavy equipment operate — voltage fluctuations and electrical interference are common. Isolation helps reduce the risk of communication errors and protects connected hardware from unexpected spikes.
Engineers typically use the NI PCI-485I/2 in automation panels, laboratory testing systems, machine control setups, and embedded control applications where consistent data exchange is required. Its dual-channel configuration also allows communication with more than one serial device at the same time, making integration easier in multi-device systems.
If you’re replacing a faulty communication card or upgrading an older setup, this model is a dependable option for maintaining long-term serial connectivity without unnecessary complexity.
At AumicTech, we understand that industrial components are often part of larger working systems. That’s why each unit is checked before dispatch to ensure it is operational and ready for integration.
Where It Is Commonly Used

PLC-based monitoring environments
Why This Model Still Matters
Even with modern communication technologies available, RS-422 and RS-485 remain widely used in industrial systems due to their reliability over long cable distances. The NI PCI-485I/2 continues to be relevant because it supports these standards in a straightforward, hardware-based format that integrates directly into PCI systems.
For facilities that rely on stable serial communication, choosing a well-supported interface card can help reduce downtime and troubleshooting efforts.
