Hi @wildbill , @TomGeorge ,
I am using 12V for multi-coin acceptor. The coin acceptor generates pulses of 5V when we connect a pull up resistance to 5V. However, I removed this 12V connector to the board, still the problem exists.
@TomGeorge , Yeah, I tried to keep the schematic easy to draw but it is difficult to troubleshoot.
However, I see it is working perfectly when no load is connected to the relays. So, the problem is with the relay side. I don’t have schematics of the 16-channel relay module.
For power supplies, I am using 12V, 10A and 5V, 1.8A.
@LarryD , This is an amazing video. I didn’t use the diode and it must be causing the inductive spiking. I will put a diode like this:
I have following questions:
- Will reducing or eliminating the inductive spiking causing from the pumps will solve resetting problem?
- Is it good like how I put the diode?
- Is a diode (1N4003) of 200 V, 1 A is sufficient?
- Is snubber circuit and the diode placed in the proposed diagram is the same? If they are not the same, do I need to use a Snubber circuit? Is Snubber circuit required for a DC system?
Thank you all of you for your time and help.
