Abstract
A circuit for sensing a plurality of inputs, each of which have a plurality of condition states, and providing a visibly coded output signal to a single indicator lamp, or the like, whereby one may readily determine the various condition states. The circuit is exemplified in an automotive voltage and current sensing system which senses the conditions of normal voltage, overvoltage, undervoltage and battery discharge. The circuit commands a single lamp to be off, to flash rapidly, to light continuously, or to flash slowly in correspondence to the particular sensed condition.
