I discovered the other day that output 2 doesn't work. At one point it did. After some testing, I've discovered that outputs 2, 3, 4, 8, 9, and 12 also don't work. At the moment this isn't serious because I'm only using 2 outputs. I'd like to use 2 more in the future, and that's ok too. But I'm limited on my room for expansion now. Of course that won't be a problem if I can't get this clicking relay problem solved!!!
Tim, what are you using to power the brain?
I've decided against trying battery power, because using batteries is not practical for use in my home. I need to power it with an AC/DC adapter. I tried 3 more wall warts today.
The ratings for all of them are 120VAC 60Hz input, and the output as follows, as well as what I measured for voltage with a DMM:
12VDC 1.5A -- measured 12.6 VDC
12VDC 2.0A -- measured 11.5 VDC
12VDC 800mA -- measured 16.4 VDC
12VDC 300mA -- measured 16.2 VDC -- this is the type of wall wart where you select your voltage and polarity. on the 9V setting the DMM gives me 12.5VDC. However, on the 9V setting, using outputs 13-16, I don't have enough power to pull the relays in but they worked when I flipped the switch to 12V. All other outputs work (i.e. the relays pull in) (other than the outputs I've already mentioned don't work) on the 9V setting. I'm only using three relays and have been moving them around from output to output so I can rule out the relays as the problem.
All outputs are centre positive.
The 16+ volts should be ok for the brain right? I see on the website it should be able to handle 17V and I realize that I am approaching it. Could that be why my outputs are all messed up? The LEDs for 9 and 12 are on all the time except when something is plugged into them. The LEDs on the outputs that work light up properly when they're turned on, none of the other outputs light other than 9 and 12 which are on full time.
I'm definitely having quite the array of problems. I'm really disappointed. I'm just amazed that of the 5 different wall warts that i've used, I have the same problem with all of them. Seriously, this thing should be able to work with a 12V adapter.
After checking out the website and reading about it, as well as all the good reviews on this forum, I bought one. I really like the idea, I like the convenience, I like the simplicity, I like the programming, and the support is great when you need help with something.
Has anybody had success with running digital outputs off a brain getting 12V from a wall wart?
