DAQ PCI Express cards

PCD-8006

With over 20 years of plug-in DAQ card design and manufacturing experience (ISA, PC/104, PCI, PCI Express), TEDIA provides a wide range of industrial data acquisition and control products.

The PCI Express bus, the successor to the conventional PCI bus, is a modern bus providing high data bandwidth (even in the basic x1 Gen1 version it can achieve throughput above 100MB/s in both directions simultaneously) and offers scalability according to device requirements (e.g. PCI Express in versions x1 to x16, or Gen2 and Gen3 variants). However, the fundamental advantage over previous buses is the dedicated data channel for each device; while for previous busses the bandwidth was shared by all devices on the bus, in case of PCI Express each device uses its own data channel and data transfers of different devices are not affected (on bus-level) by each other.

However, PCI Express bus (against PCI bus) does not accelerate data transfer in real-time applications, when the program reads several input values from the card, and writes the control intervention to the outputs. PCI Express achieves high bandwidth throughput only with continuous block data transfer, while with one-time access to registers works a bit slower than a conventional PCI bus. In other words, the high PCI Express data bandwidth will not be used in real-time control application, when whole algorithm runs on a PC.
