Hi.
Objective:
So essentially an audio signal sensing relay, with a delay function. I could have one relay trigger another relay but that is not idea.
I found:
Any advice appreciated.
Objective:
- Cut mains power (Open 220V circuit) to n devices when no audio received after 600 seconds.
- Close circuit when audio received.
So essentially an audio signal sensing relay, with a delay function. I could have one relay trigger another relay but that is not idea.
I found:
- ST-ACR1 ‐ Line-Level Audio Controlled Relay - 0.5 to 5 s (Expensive and requires another HV relay).
- 12V 0-10A DC Current Detection Module Current Sensing Detecting Delay Relay G8T0 | eBay (not sure about this, the Chinglish a little confusing)
Any advice appreciated.
Hi,
You can do it easily if you are willing to write a program/sketch like Arduino. You can use an op amp to amplify the input signal to at least from 1 to 5 volt so the micro analog input can read it. Write a routine to energizes the relays in the sequencing that to want to enable them. Easy.

If I pay for p&p + materials can you send me one?
Hi,
I can help you in the programing but my advice to you it is try to get an Arduino UNO and start learning it. There are many many hobbyist today that are using it in their design/projects. It is easy to learn and there are a lots of web side with tutorials on how to use and how to programming it.
Try to do an schematic on what do you want and the voltage specifications for the components that you are going to use.

I've bought 2 of them for my 3D printer bcos they keep blowing on me, different place each time.
I unfortunately have a passionate dislike for Arduino and the Intel Edison. RPi is OK.
Any other advise apart from an UNO, seems a bit overkill?
Hi,
You may need to sit down and analyzes why they are keeping burning up. Remembered that you need to understand the input/output specification and make sure they are not exceed. Today all my projects are built using a micro. By using a micro you will minimizes the components count since most of the logic are done in the programming.
I already have built 20 projects using the Arduino and up to today never had one fail on me. Also you need to understand how to interface them to the outside world when using high voltage. They do not like high voltages/spikes.
Write an schematic what do you want to accomplish and I will go thru it to see how to interface the micro to your project. Please make sure provide the voltages.

MSADP-2
Audio Input:
Hi Level & Lo Level
Audio Output: Lo Level with gain control
Turn on delay: up to 6min.
That looks perfect, but where can I buy it?

1.- Time the motor slid and sent current back.
2.- Came back after the printer had been printing for a while and it was off... no idea what happened.
I do buy the chinese clones.
It will be for sale on Ebay
next month at this store:

12v Trigger standards; the below device has a 12v/100mA trigger in/out.
Does that mean it triggers once, like a toggle (on and then off after x seconds) or does it keep supplying 12v@100mA while it's on?
Does it need to have 12v in for it to trigger?
Thanks.

An externally hosted image should be here but it was not working when we last tested it.
For anyone googling this in the future; the Yamaha WXC-50 puts out a constant 11.97v while on.
When Standby is triggered it slowly decreases voltage to ~1v in 8 seconds, then another 10 seconds to a background 80mV.
Well that's what mine does.
The WXC-50 has an Alexa skill, so I just need to say Alexa, turn on the tubes, the amp has a 30 second preheat so it takes that long for the front speakers to kick in, but the sub starts in ~2 seconds.
