### 4. Functionality

The LPCIe‑7230 provides optically isolated digital input and output channels for interfacing industrial control signals with a host PC. Each input channel uses an opto‑coupler to detect external voltage levels up to 24 VDC, ensuring electrical isolation and noise immunity. The non‑polarized input design allows flexible wiring without concern for signal polarity.

Output channels employ Darlington transistor arrays configured as open‑collector sinks. External devices such as relays, solenoids, or indicator lamps can be driven directly using an external DC supply (5–35 V). The card’s isolation barrier protects the host system from voltage spikes and ground potential differences.

Typical Applications:
- Factory automation and process control
- Machine status monitoring and alarm systems
- Relay and solenoid actuation
- Industrial equipment interfacing
- Data acquisition and test systems
- SCADA and HMI integration

Compatibility:
- Compatible with ADLINK’s DAQPilot, DAQBench, and DAQMaster software suites.
- Supports integration with LabVIEW™, MATLAB®, and Visual Studio environments.
- Fully plug‑and‑play compliant with PCI Express® systems.
