Watchdog timers help avoid system failures

Edited by the Electronicstalk editorial team Jul 3, 2009

Acces I/O Products is announcing a series of dedicated watchdog timer boards for PC/104-based embedded systems - Model P104-WDG-CSMA.

This watchdog board will stand guard over a system and is designed to help avoid costly system failures.

The board can be used to monitor the operation of an application program as well as the operating system and will initiate a system reset in case of lockup.

In addition, the P104-WDG-CSMA can monitor and control a variety of system hardware parameters such as temperature, voltage, fan speed, humidity and more.

The board was designed to allow for complete peace of mind when planning a PC/104-based embedded system.

Applications include kiosks, industrial automation, military/mission-critical, asset management and tracking, retail, medical, embedded OEM, temperature measurement and many others that require self-reliant embedded systems.

The P104-WDG-CSMA includes an assortment of attributes to supplement the standard features expected from a watchdog timer.

These include one general-purpose optically isolated input, two isolated digital outputs to control/switch external events, two non-isolated digital outputs, two general-purpose A/D inputs, and even a security light sensor that can be used to detect if the darkened interior of an enclosure is opened.
