The Redstone Inventory Counter sends an R64 signal (Or a standard on/off redstone signal) based on the total number of items in a Chest which is located at the Redstone Inventory Counter's front. The signals are designed for use with Redstone Numeric LED Displays and any other R64 compatible blocks. When the output is a block which only accepts a standard redstone signal it will output an on value when the inventory contains at least 1 item.
