### 4. Functionality

The LPCI-7230 provides electrically isolated digital input and output channels for interfacing with external industrial devices such as sensors, relays, solenoids, and actuators. Each input channel can detect voltage levels up to 24 VDC, while each output channel can drive loads up to 35 VDC using open-collector Darlington transistors.

Operation Principle:
- Digital Inputs: Each input channel is optically isolated from the system bus, preventing ground loops and protecting the host PC from voltage transients. The non-polarity design allows flexible wiring without concern for signal polarity.
- Digital Outputs: The outputs use Darlington transistor arrays capable of sinking up to 500 mA per channel. External power (VDD) is required to drive the output loads. The open-collector configuration allows direct control of relays, lamps, or other DC loads.
- Interrupts: Two interrupt sources are available on input channels 0 and 1, enabling event-driven control and monitoring.

Typical Applications:
- Industrial automation and process control
- Machine status monitoring
- Relay and solenoid actuation
- Data acquisition and test systems
- PLC interfacing and SCADA systems
- Safety interlock and alarm systems

Compatibility:
- Compatible with ADLINK’s DAQPilot, PCIS-DASK, and DAQ-MTLB drivers.
- Supports integration with LabVIEW™, MATLAB®, and Visual Studio environments.
- Works with Windows 7/Vista/XP/2000/2003 Server and Linux distributions.
