PCI-1750 Features 32-ch Isolated Digital I/O and Counter Card

PCI-1750
32-ch Isolated Digital I/O
and Counter Card
Features
 16 isolated DI and 16 isolated DO channels
 High voltage isolation on all isolated channels (2,500 VDC)
 High sink current on isolated output channels (200 mA/channel)
 Supports dry contact or 5 ~ 50 VDC isolated inputs
 Interrupt handling
 Timer/counter interrupt capability
Introduction
PCI-1750 offers 16 isolated digital input channels, 16 isolated digital output channels, and one isolated counter/timer for the PCI bus. With isolation protection of 2,500 VDC, and
dry contact support, PCI-1750 is ideal for industrial applications where high-voltage protection is required. Each I/O channel of the PCI-1750 corresponds to a bit in a PC I/O port.
This makes PCI-1750 very easy to program. This card also offers a counter or timer interrupt and two digital input interrupt lines to a PC. So you can then easily do configurations
by software.
Plug & Play
PCI-1750 uses a PCI controller to interface the card to the PCI bus. The controller fully implements PCI bus specification Rev 2.1. 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.
On-board Programmable Counter/Timer
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.
