This watchdog card monitors the Hard Drive Activity LED and resets a programmable timer every time the hard drive is accessed. If there is not at least one hard drive access within the selected period of time, the watchdog will reboot the computer by essentially closing the reset switch with a relay. The card is intended for any computer (PC, Mac, other) in which no hard drive activity would indicate a fault or a “hung” computer. It does not require any software.

Multi Purpose MPU / Dual Relay Card (Model L362)
This amazing little workhorse finds its way into all sorts of diverse applications because of its simplicity and versatility. It combines a custom programmable microprocessor and 2 solid, reliable DPDT relays with a host of input and power supply / handling options. The PIC micro can be easily programmed to command the relays depending on up to 3 external inputs monitoring switches, voltage changes, serial data messages, or whatever else you can imagine. The relays can independently control 2 120vac or 12VDC, or any other AC or DC voltage from 0 to 120. They can also switch speakers, communications, and many other signals. The fuse and metal oxide varistors are custom selected to provide protection for whatever you are automating.
