Introduction
PCI-1751U is a 48-bit digital I/O card for the PCI bus. Its 48 bits are divided into six 8-bit I/O ports and users can configure each port as input or output via software. PCI-1751U also
provides one event counter and two 16-bit timers, which can be cascaded to become a 32-bit timer. PCI-1751U adds a universal PCI interface for 3.3 V compatibility.
Fulfilling the True Requirements of Industrial Applications
With two practical functions, the PCI-1751U fulfills the true requirements of industrial applications. When the system is hot reset, (power is not shut off), the PCI-1751U can either
retain the last I/O port setting and output value, or reset to its default configuration, depending on jumper settings. This function protects the system from wrong operations during
unexpected system resets. Additionally, the PCI-1751U supports both dry and wet contacts so that it can easily interface with other devices.
Interrupt Handling Capability
Two lines in each I/O port (C0) and two of the three counter outputs (Timer 1 and Counter 2) are connected to the interrupt circuitry. Two interrupt request signals can be generated
at the same time and the software can service the two request signals by ISR. Moreover, a pin in the connector can output a digital signal simultaneously with the card generating an
interrupt, and users can utilize this function to trigger external devices with the interrupt.
