Digital I/O and counter card for HV applications

February 2004 Industrial Computer Hardware

The PCI-1750 32-channel isolated digital I/O and counter card from ProMicro is ideal for industrial applications where HV protection is required. The card offers 16 isolated digital input channels, 16 isolated digital output channels and one isolated counter/timer for the PCI bus.

Each card has 2,5 kV d.c. isolation protection and dry contact support, and each I/O channel corresponds to a bit in a PC I/O port, making the card easy to program. The card also offers a counter or timer interrupt and two digital input interrupt lines to a PC, which can be easily configured through software.

A PCI controller is used to interface the card to the PCI bus. The controller fully implements the PCI bus Rev 2.1 specifications. All bus relative configurations, such as base address and interrupt assignment are automatically controlled by the software. No jumper or DIP-switch is required for user configuration.

The PCI-1750 provides a programmable counter/timer for generating periodic interrupts to the host computer. The counter/timer chip is an 82C54, which includes three 16-bit counters based on a 10 MHz clock. One counter is used to count events coming from the isolated input channel. The other two are cascaded together to make a 32-bit timer. Typical applications include industrial on/off control, contact closure monitoring, switch status sensing, BCD interfacing and digital I/O control.
