PCI-7442/7443/7444
High-density 128-CH Isolated DIO/DI/DO Cards
Introduction
Responding to the industry’s need for high-density digital input/output modules, the ADLINK PCI-744X DIO
card series delivers up to 128 opto-isolated channels for a wide range of demanding PCI-based applications.
The PCI-744X card series comes with 64 (PCI-7442) or 128 (PCI-7443) opto-isolated digital inputs and 64 (PCI-7442)
or 128 (PCI-7444) opto-isolated digital outputs. With a 1250 V
RMS
(excluding cables) channel-to-system isolation protection,
these cards are shielded from damage caused by accidental contact with external voltage while promoting simple ground
connections. All input channels are identical non-polarity with each line isolated and suited to collect digital inputs even
at high-noise environments. Featuring a Change-of-State (COS) interrupt function, the PCI-7442/PCI-7443 instantly
generates an interrupt request to the PCI controller when it detects a sharp change in the logical state of any of its digital
inputs.
For easy identification in systems with multiple DIO cards installed, the cards are also equipped with a board ID design
that enables fast and convenient card detection and troubleshooting.
