High-density 128-CH Isolated DIO/DI/DO Cards

Key Features

Support universal 32-Bit 3.3V and 5V PCI bus, plug-and-play

High-density, opto-isolated digital input and/or digital output

1250 VRMS isolation voltage

Programmable Change-of-State (COS) detection for all digital input channels

1250 VRMS isolation voltage

Voltage protection for all isolated digital inputs

Up to 250mA high capability sink current for all isolated output channels

Up to 300mA sink current on each isolated output channel

Responding to the industry’s need for high-density digital input/ output modules, the ADLINK PCI-7442/7443/7444. PCIe-7442 DIO card series delivers up to 128 opto-isolated channels for a wide range of demanding PCI-based applications.

The PCI-7442/7443/7444. PCIe-7442 series comes with 64 (PCI/PCIe-7442) or 128 (PCI-7443) opto-isolated digital inputs and 64 (PCI/PCIe-7442) or 128 (PCI-7444) opto-isolated digital outputs.

With a 1250 VRMS (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/PCIe-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.(excluding cables) channel-to-system isolation protection,
