Industrologic, Inc., announces the release of their UWDTPC Universal Standalone Watchdog Timer for internal use in a variety of personal computer units.
The Industrologic UWDTPC is a standalone watchdog timer circuit that can be triggered with a wide variety of digital output signals or LED drive circuits from a microcontroller or single board computer, or with RS-232 serial data from any communication protocol.
It can be used to increase the reliability of nearly any single board computer or personal computer system by monitoring a signal, and activating the reset circuit if the signal is no longer present.
The UWDTPC has been designed to allow easy installation inside typical computer enclosures containing motherboards and power supplies, including personal computers and Mini ITX systems.
It is based on discrete logic and relay drive circuitry and is powered by 5 volts from a common PC disk drive/floppy disk drive connector. It has a 2 pin .1 inch header for triggering with a digital input (or hard disk activity LED) signal and a 10 pin header matching PC serial port connections for triggering with RS-232 data.
The relay's normally open isolated relay contacts are provided at a 2 pin .1 inch header for connection to a reset signal, and LED indicators indicate the status of the trigger and relay activations.
