Just found a a different module on ebay that looks like it does the input/output frequency alignment onboard and just takes a PWM signal for control
Ah ok, i assumed this zero cross input would be needed so the PWM wave output from brucontrol and the AC supply wave would be aligned so it knows wher...
This is the module i was looking at
The 1N4001 diode across each contactor coil and extra wire between control ground and main earth terminal has resolved my issues. All working well now...
I stand corrected, it is only when the contactors drop out that this occurs not when they pull in. Have ordered some diodes so will try that. I will t...
This is the power supply i use /p> It powers the arduino, a 3a pump, small panel alarm and 3x contactor coils
In your example schematics you have the mains earth connected to control ground point, i was unsure as to wether this was a good idea during wiring so...
I attached a small video to show what happened thats probably why it failed. Ok, no worries. That explains why i couldnt get it to work. Will wait for...
Thanks, i thought that must be a typo. Says 5mA here:
Looking through my suppliers catalogue i cant find any SSRs with 5vdc control and 5mA or less trigger current
