The Swiss-made Yocto Watchdog DC Timer is a USB-controlled device. When installed across a DC power cable, it can cut and restore the power whenever the control application fails to contact it.
The typical application is to power-cycle a crashed computer. As long the control application running on the the computer contacts the device on a regular basis, the power stays on. If, for some reason, the application stops to contact the device, the power will be cut for a short time. The will cause the computer to reboot.
The integration of this watchdog into existing solutions is easy, given that it does not require a device driver. The watchdog timer can be reset either using a command line, or using a simple function call to Yoctopuce library. The Yoctopuce library is available in most programming languages, in source code form.
This device can also be used as a cheap solid-state relay. Please note that this device is not isolated: the output and the USB share the same ground.
This device can be connected directly to an Ethernet network using a YoctoHub Ethernet, to a WiFi network using a YoctoHub Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub GSM.
