I have a fotek SSR-25 relay I want to use to control a light (just a 120V led bulb).
The wire connected to the #1 contact is 120vac. I have nothing connected to the load side (#2). The inputs are driven by a proximity sensor:
Edit: after trying the relay manually by connecting the load and then touching the 12V input to the contacts, I was able to determine that the relay does, in fact, work.
Which is powered by a transformer at 12vdc:
The sensor can be activated by a hand coming within 0.75".
Please disregard the sloppiness of the wiring, as this is just in an experimental state. Once I get it working, I will button everything up properly.
I have two problems.
- The relay has 120 vac across both contacts, regardless of what voltage is being applied to the inputs. (Edit: this isn't actually a problem)
- The proximity sensor seems to work fine I free space, but wood appears to trigger it (???) which makes it inoperable when mounted as shown in the picture.
Edit: I still haven't quite solved the problem of getting the sensor working while next to materials, but I'm punting on that for now. What seems to be preventing the sensor from activating the relay is that the relay contacts only show a voltage difference of ~20mV, which isn't anywhere near large enough. I don't understand why it's doing that, though. Here's the wiring diagram and ratings:
This diagram (which is pretty much all the specs offered by Anigmo) seems to indicate that the voltage across t he relay contacts should be as high as 48VDC, but it's orders of magnitude lower than that.
Does anyone have any suggestions as to what I might be doing wrong, or how better to diagnose the problems?
