4. Functionality
The PWDOG2N Watchdog PCI Card functions as a hardware-based system supervisor. It continuously monitors system activity through software signals or hardware triggers. When the system operates normally, the watchdog timer is periodically reset (“kicked”) by the host software. If the system fails to send the reset signal within the configured time interval, the watchdog timer expires and activates one or both relay outputs.
These relays can be configured to perform various actions, such as:
- Triggering a system reset or power cycle
- Activating an alarm or indicator
- Controlling external devices (e.g., fans, lights, or safety interlocks)
Use Cases and Applications:
- Industrial automation systems requiring continuous uptime
- Embedded control systems where unattended operation is critical
- Server or workstation monitoring for automatic recovery from system hangs
- Remote monitoring and control systems
- Process control environments where hardware-level fault detection is essential
- Laboratory or test setups requiring timed relay activation or fail-safe control
Compatibility:
- Compatible with standard PCI slots (32-bit, 33 MHz)
- Works with most operating systems that support PCI hardware access (Windows, Linux, real-time OS, etc.)
