lostsoul Posted January 2, 2017 Report Share Posted January 2, 2017 I have a wire to DI-2 and a sensor ground be connected to a water level switch ... want to incorporate a indicator LED, so, do I connect the the -ve ( from the LED ) to the wire connected to DI-2 and the +ve to +12v ? ( I have a resistor on the +12v Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 3, 2017 Report Share Posted January 3, 2017 Yes, my logic says your proposed set up is correct and should work as expected. LED off and DI is high when switch is open, LED on and DI goes low when switch closes. Quote Link to comment Share on other sites More sharing options...
