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 independantly
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.
