SHELLEY INDUSTRIAL AUTOMATION LM3 MULTI-BEAM Series 3 and 4-Wire Logic Module - ON/OFF (Light or Dark Operate)

The LM3 is an on-off logic module that has the ability to be programmed for either LIGHT operate or DARK operate. It comes with a jumper wire installed: with the jumper in place, the output is DARK operated; with the jumper removed, the output is LIGHT operated. The LM3 is the most commonly used logic module when no timing function is desired, particularly if it is not known at the time of ordering which mode (LIGHT or DARK operate) will be needed.
