ADLINK Technology PCI-7200 Series PCI Digital I/O Cards include 8-CH, 16-CH, 24-CH, 32-CH, 48-CH, and 96-CH digital input/output (DIO) peripheral component interconnect (PCI) cards. The PCI-7200 12MB/s High-Speed 32-CH DI & 32-CH DO Cards offer high-performance designs and state-of-the-art technology, making these cards suitable for high-speed data transfer and pattern generation applications. The PCI-7250/7251 8-CH Relay Outputs & 8-CH Isolated DI Cards feature nonpolarity, optically isolated digital input channels, and may be set to use RC filter or not, making them suitable for collecting digital inputs in noisy environments. The PCI-7230 32-CH Isolated DIO Cards provide a 2,500V optical isolation protection and a wide input range for easy sensing of the status of external devices. The PCI-7296/7248/7224 96/48/24-CH Opto-22 Compatible DIO Cards feature header connectors that are fully compatible with industry Opto-22 standard, so that they can utilize the Opto-22 external devices. And the PCI-7256 16-CH Latching Relay Outputs & 16-CH Isolated DI Card offers the advantage of power saving and features unchanged status even when the system power is turned off, so that the PCI-7256 is suitable for critical applications which need to keep output status when fault conditions happen.
