Long and short is:
24 VDC & 120 VAC in and 5 VDC out
Whats the deal on out put modules or not using them?
Thanks
The outputs work more like a relay, common goes to pin 3, when +5vdc goes to pin 4, a triac fires on the AC modules and a transistor on the DC connecting pin 1 to pin 2. If that makes sense. I've never had to think about how they work before.
I wired up all 4 variations today. The input modules switch the - not the +. The DC output module worked fine but the AC did not want to accept a load. Not sure if I'm missing something but with 5vdc applied I would get 120vac through the module but with any load at all it would struggle. The LED with a rectifier circuit would light very dim and with a small relay it would only pick it half the time. I tried 3 modules with the same results. The circuit in the link was the only way I could get a consistent, brightly lit LED every time 5vdc was applied. Obviously you wouldn't want to leave power on this circuit all the time but opening the whole circuit wasn't working, seemed like maybe the cap needed to stay charged? Doubt I have to tell you but I'm not an engineer.
Think we have impose more of a load on the AC output. Correct me if I'm wrong. The LED draws around 20 MAs which may not turn on the module. Maybe a small transformer in series with the IO will get it going, Use the out-put to drive an LED?
