I have an application where I want to establish a gate on a conveyor line. I would like to open the gate only when a barcode scanner has
successfully scanned the barcode of the product on the conveyor, at the gate (ie do not let product go upstream until it has been scanned
into the lot tracability system). I was envisioning using a SSR to receive the scanned signal, driving an input on a small plc. Has anyone ever done something like this? I am having trouble trying to get an actual voltage/current from the scanner....
