National Instruments PCI-DIO-32HS Digital I/O Device

The PCI-DIO-32HS, also known as the PCI 6533, (Part Number: 777314-01) is a completely jumperless, switchless Digital I/O Device from National Instruments. This model is designed for CompactPCI or PXI chassis and PCI busses. Powered with the NI proprietary MITE PCI interface, the PCI DIO-32HS offers bus-master operation, burst PCI transfers, and high-speed DMA (Direct memory access) controllers.

This Digital I/O Device comes equipped with the NI DAQ-DIO chip. The National Instruments DAQ-DIO chip comes equipped with handshaking, pattern generation, and two separate channels of digital input and digital output. Each channel offers a selectable data path width, 16 and 32-bit counters, a handshaking controller with six timing protocols, 24 mA outputs, star /stop trigger detection, and more. The Pattern I/O and Handshaking I/O functions of the PCI DIO-32HS allow the user to input or output patterns with timing control.

The 32 digital input/output lines offered by this device are divided as four 8-bit ports. For handshaking or pattern I/O, these ports can be used in configurations of two 8-bits or two 16-bit groups or one 32-bit group. The channels have a maximum rate of up to 2 MHz for pattern I/O, and voltage levels of 5 V TTL/CMOS. The digital transmission on PCI DIO-32HS is managed by a single 68-pin male SCSI-II cable connector. Moreover, this Digital I/O Device enables the users to select power-on states for the data and control lines independently.

This device utilizes the RTSI bus or the PXI trigger bus for receiving and sending trigger and clock signals to and from other connected devices. Thus, the PCI DIO-32HS can also be utilized for the construction of synchronized systems with a massive number of digital input and output lines.
The PCI DIO-32HS operates using the NI-DAQ driver software which is compatible software packages/ application development environments (ADEs) like LabVIEW, LabWindows/CVI, ComponentWorks, or VirtualBench. The device has a recommended operating temperature range of 0 to 55° C and measures 6.9 x 4.2 in. in physical dimensions.

While the status of the PCI-DIO-32HS is considered Obsolete by National Instruments, the Digital I/O Device will remain available in perpetuity for both purchase and repairs with Apex Waves! Request a quote today.
