This barcode scanning module can be used as a standalone device or integrated as a component in a larger system. We employ either Laser or Vision based scanners. The unit comes pre configured with normally open and normally closed relay outputs which switch when a barcode that differs from the trained code is read. The module is fully programmable if an alternate method is desired. Training is easy and is accomplished with the push of a button. This module can be used on labels, cartons, boxes, pallets, or anything else with a barcode.
