PCI-1750
32-channel Isolated Digital I / O and Counter Card
Features
· 16 isolated DI and 16 isolated DO channels · High voltage isolation on all isolated channels (2500 V DC) · High sink current on isolated output channels (200 mA / channel) · Supports dry contact or 5 ~ 48 VDC isolated inputs · Interrupt handling · Timer / Counter interrupt capability
Introduction
The PCI-1750 card 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, the PCI-1750 is ideal for industrial applications where highvoltage protection is required. Each I / O channel of the PCI-1750 corresponds to a bit in a PC I / O port. This makes the PCI-1750 very easy to program. This card also offers a counter or timer interrupt and two digital input interrupt lines to a PC. Users can easily configure them through software. · Input range: 5 ~ 48 VDC or dry contact · Isolation voltage: 2, 500 VDC · Throughput: 10 kHz
Digital Output
· · · · · 16 Optically-isolated outputs Output range: Open collector 5 ~ 40 VDC Sink Current: 200 mA max. per channel Isolation voltage: 2, 500 VDC Throughput: 10 kHz
PCI-Bus Plug and Play
The 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.
Programmable Counter / Timer
· One 32-bit timer · One 16-bit optically-isolated counter - Shares pin with isolated input 15 - Throughput: 1 MHz max. - Isolation voltage: 2, 500 VDC
On-board Programmable Counter / Timer
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.
