PCI-7432 32 CH Isolation DI & 32 CH Isolation DO The PCI-7432/33/34 series products are the highest density digital I/O cards for the PCI bus. To use the plug & play PCI bus to replace the old ISA architecture is a trend. All the I/O ports are accessed by 32-bits I/O instruction, therefore increasing the data throughput rate. The PCI-74xx series cards content 64 isolation DIO channels and using the rugged 100-pin SCSI-II connector. The photo-isolators are used to isolate the signals between host and the I/O device, the 5000V rms high isolation voltage protect the host computer. They are very suitable for harsh industry applications. The isolation DO channels are driving by Darlington transistors with 500 mA current sink capability, the DO channels are very suitable to drive the relay or high power lamb directly. The voltage input for the isolation DI channels can be up to 24 volts. These DI channels are protected by the on board 1.2KW resistors. The full line software supports for Window 95 and Window NT OS let users easy to develop the application. The software development for PCI-7432 series products will be forward compatible to their further Compact PCI version.   Specifications Optical Isolated Input channels Numbers of channel: 32 for PCI-7432 64 for PCI-7433 Input voltage: 0-24V dc Logic H: 3~24V Logic L: 0~1.5V Input resistance: 1.2KW @ 0.5W Isolated voltage: 5000 V rms Throughput: 10KHz (0.1ms) Interrupt sources: Ch#0 and Ch#1 of DI channels Optical Isolated  Output channels Numbers of Channel: - 32 for PCI-7432 - 64 for PCI-7434 Output type: Open collector Darlington  transistors, Device: TD62081 Sink current: - 347mA/ch typ.,500mA/ch max.

The importance of isolation!

The isolation means the power and signal lines on the host computer have no connection with the external signals. The electronics digital signals is transmitted to/from the external devices by the photo-couplers. The isolation voltage of the photo couplers on the PCI-743X series cards is 5000 V rms. Therefore, even the external devices are destroyed by electrical shock , the host computer is under fully protected.
