I have a standard dual channel Arduino solid state relay module that is powered by 5volts.
I tried connecting it to Arduino to test it. Dc+ to 5v , Dc- to gnd and one of the inputs to pin 4. The relay is getting powered and all voltages read fine at terminals. The program toggels the relay every 5 seconds and I can see it working as the led on relay against the input comes on and goes off in 5 seconds. However if I use multimeter to check continuity at output terminals I get nothing. I tried both relays on the module and still nothing. What could be wrong ?
