PCIe Watchdog Thwarts System Failures

ACCES I/O’s PCIe-WDG-CSMA watchdog timer card can monitor operation of an application program as well as the operating system and can be configured to initiate a system reset in case of lockup. The card can also monitor a variety of system hardware parameters such as voltage, humidity, temperature, light, and more. Applications include kiosks, industrial automation, military/mission-critical, asset management and tracking, retail, medical, embedded OEM, and temperature measurement for starts.


In addition to the standard features of a watchdog timer, the PCIe-WDG-CSMA includes an assortment of additional attributes such as four general purpose optically isolated digital inputs, two isolated FET outputs to control/switch external devices, two non-isolated digital inputs/outputs, and six dedicated A/D inputs which includes a security light sensor that can be used to detect if the darkened interior of an enclosure is opened. Available accessories include cables and screw terminal breakout adapter boards. Customization options include conformal coating, custom software, product-labeling, and more upon request.
