That's one of the bugaboos with Chinese direct products. Products that aren't retailed through natives in the country of sale suffer from poor descriptions to nearly no descriptions. Sending queries to the Chinese seller is an exercise in futility.Okay,going with this latest module
Only thing is,where to connect gsm + and -
I see dc + and -,those are for power supply and on the output it isn't very well explained how to connect a motor ?
Do i need to solder those extra wires to the optocoupler ?
Ok,now i get it all
Gsm transmits signal to ir every second,it is not continious
At the motor,will it also run every second and not continious ? Or this opto, like PIR has a certain delay before switching off
Also,what symptoms can occure by having slow optocoupler with fast mosfet request ?
Ivan
Ivan, please select one.when i connect it as shown above i get 12v voltage on this wires that go to this button,and when i connect ringer it stays always on
only when i disconnect wires it works as it should
Ivan, did you make sure you clicked the drop down box and selected the 12V model? Also, when it arrives please don't power it up until you post to this thread and tell us if it came with any further instructions or tech data. In particular I want more info regarding the Optocoupler and its input circuit. If you can read the Opto part number please post it. I also want you to take Ohmmeter measurements from the Opto's socket to the Opto's input pins. This is to insure they included a current limiting resistor for the Optocoupler's LED. It's very unlikely that they didn't but it can't hurt to check it.
Chris
The Opto input is the White (2 pin) connector. Pos(+) is the top (Red) wire. Neg(-) is the same White connector (Black wire) directly under the Red. A 560Ω will work fine.+ Is top left and - Is bottom left ?
Electronic shop Is closed for a month
I only have 560ohm resistor
Can i use it ?
OK Ivan. That test confirms that there's a current limiting resistor on the board because I don't think any of the OptoCouplers I'm familiar with employ an integral resistor.10.1 volts
