Proper usage for LFM-20


I’m looking at using an LFM-20 to control a relay coil. The power to the coil will be 24VDC. The description refers to this unit as an “Isolated Contact Fixture Module” which leads me to believe it will work for my application. i.e., it’s a mechanical contact not connected electrically in any way to the controlling circuit. Yet the manual states that the load must share the neutral with the device. Has anyone tried it as an isolated contact? Or can anyone clarify this seeming contradiction?
