4. Functionality

The PCI-7230 provides isolated digital input and output channels for interfacing with external industrial devices such as sensors, relays, solenoids, and actuators. Each input channel is optically isolated to prevent electrical interference and protect the host system from voltage surges. The non-polarity input design simplifies wiring and allows flexible connection to various signal sources.

The output channels use Darlington transistor open-collector configurations, capable of sinking up to 500 mA per channel. External power (5–35 VDC) must be supplied to the VDD terminal to drive output loads. The card supports external interrupt generation on input channels 0 and 1, enabling event-driven control in automation systems.

Typical Applications:
- Industrial automation and process control
- Machine status monitoring
- Relay and solenoid control
- Data acquisition and digital signal interfacing
- PLC and SCADA system integration

Compatibility:
- Fully compliant with PCI Local Bus Specification Rev. 2.1
- Plug-and-Play configuration via system BIOS
- Compatible with ADLINK’s DAQ software suite and third-party environments such as MATLAB® and LabVIEW™
