### 4. Functionality

The PCI-7260 operates as a high-current digital I/O interface for industrial control systems. It provides eight relay outputs for switching high-voltage or high-current loads and eight optically isolated inputs for monitoring external signals.

Operation Principles:

- Relay Control: Each relay is controlled via software or hardware registers. A logic “0” energizes the relay (SET), while “1” de-energizes it (RESET).
- Emergency Shutdown: A dedicated input triggers a predefined safe relay pattern, independent of the host system.
- Watchdog Timer: Monitors system activity; if the host fails to reset the timer, relays revert to a safe state.
- Change-of-State Interrupts: Detects transitions on input channels and generates interrupts for event-driven control.
- Initial State Configuration: DIP switches define relay states upon power-up.
- External LED Outputs: Provide visual relay status outside the chassis.

Typical Applications:

- Industrial ON/OFF control
- Machine and process automation
- Laboratory instrumentation
- External relay driving and signal switching
- Limit switch and contact monitoring
- Integration with A/D and D/A cards for complete data acquisition systems

Compatibility:

- Compatible with Windows 98/NT/2000/XP via PCIS-DASK driver
- Supports LabVIEW through DAQ-LVIEW PnP VIs
- Programmable via C/C++ libraries for DOS and Windows environments
