ADLINK PCI-7434 64-Channel Isolated Digital I/O PCI Card
The ADLINK PCI-7434 is a 64-channel isolated digital I/O PCI card built for industrial automation applications. The model provides 64 digital output channels through open collector Darlington transistor drivers. The model isolates each channel electrically to protect the host computer from field side voltage spikes. Each channel on the card sinks up to 500 mA at 100 percent duty cycle. All 64 channels together sink 500 mA when operating at 20 percent duty cycle. Each driver chip on the card dissipates a maximum of 2.25 watts across eight output channels. The card accepts an external field supply voltage between 5 V and 35 V.
The PCI card organizes its 64 output channels into eight driver chips of eight channels each. This arrangement lets system designers plan heat dissipation and current loading per chip group. The open collector Darlington output stage lets each channel drive relays solenoids and indicator lamps directly. The designers can size field wiring and power supplies around these per chip limits. The model provides 2500 VRMS isolation between field wiring and the host computer bus. The data transfers on the card rely on programmed I/O for direct register level access.
The PCI-7434 Digital I/O PCI Card connects to field wiring through a 100-pin SCSI-II female connector. This connector accepts standard SCSI-II cables for wiring to external terminal boards. It operates reliably across an ambient temperature range of 0 °C to 60 °C. The card withstands storage temperatures between – 20 °C and 80 °C without damage. The relative humidity tolerance for the model extends from 5 percent to 95 percent non-condensing. The board draws 560 mA typical current from the host 5V supply rail.
The card measures 156 mm by 106 mm excluding its connectors and brackets. This compact footprint fits standard PCI expansion slots inside industrial computers and control chassis. The model supports Windows 7 and Windows 8 operating systems in both x64 and x86 editions. The Linux operating systems are also supported for the model. ADLINK supplies drivers and software development kits for LabVIEW MATLAB C/C++ Visual Basic and Visual Studio .NET. The AD-Logger utility software works directly with the card for logging digital output states during operation.
