LM5

The LM5 is a true on-delay type Logic Module. The input signal must be present for a predetermined length of time before the output is energized. The output then remains energized until the input signal is removed. If the input signal is not present for the predetermined time period, no output occurs. If the input signal is removed momentarily and then reestablished, the timing function starts over again from the beginning. A light/dark operation selection jumper is included. The standard time range is adjustable from 1.5 to 15 seconds (field adjustable) and other ranges are available. The LM5 is often used to detect jams on a conveyor line, where a beam broken for longer than a preset period of time implies a product jammed in the light beam.
