Hello. I'm hoping someone can assist me with an issue that has me saying words that I try very hard not to say. I have a printing press that uses a lot of photoelectric sensors to limit strokes and notify the main controller that the motion is complete. The sensors use standard telephone wires to send signals. I would like to delay a signal when one particular sensor is tripped and was wondering is there is a device/component that is as simple as unplugging one end of the phone cable and inserting it in the middle then reconnecting with a second cable to the original destination? Ideally, it would allow me to vary the delay until I found the ideal value -- 1/2 second to 5 seconds would be plenty. I know very little of electronics and have tried unsuccessfully (with some slightly less amateurish third party help) to control it on the power supply side with no success -- there are six separate boards, among other components, all tied together with lots of logic that requires all motions at six locations to be complete before activating the next step. The particular sensor I want to delay is the one that says "ok - the table is in the right place so start all the motions" so it isn't actually in the middle of potentially interfering signals. Thanks so much in advace for any input!
