Greetings! I need somebody double-check what I have. I'm really out of ideas.
- I have purchased 2 modules of 2-channel SSR module (based on Omron G3MB-202P). They all were sealed. Package was not damaged.
- I have connected 5v to DC+ and DC-. I was expecting that nothing's going to happen (because it's just power). Actual result was 2 LED started glowing red (like if the relay was turned on). I have measured voltage on the Omron module input (legs 3 and 4) and it was 1.79v.
- When I have connected a simple 220v light bulb to the output, nothing happened.
- If I set high (5v) to CH1 of the module, then the following happens: (1) corresponding LED stops glowing, or becomes very dim. (2) voltage on the Omron module input (legs 3 and 4) goes down to 1.14v. And obviously the relay stays closed.
If I bypass all the circuits of the module and connect 5v into the Omron relay (legs 3 and 4) then it opens successfully and my bulb turns on.
Am I connecting the entire module incorrectly? Maybe there are other owners of such a module?
Any info would be helpful!
