When choosing a 24 vdc power supply is it important for the output amperage to match the the device it will be supplying power to? Example: Would a 24vdc / 100ma power supply be ok to operate a timer relay rated (24vdc /8ma control) or should I find a combo closer to the same amperage? |

The current capability of the supply should be more than that required by the load. When using a feeble load on a really beefy supply, ensure that there is some protection. In the example given the combination is okay. |

Thank you for your response Mike. I recently received an invitation to receive your online text book. I would love to sign up for something like this but most of these things assume I'm further along in electronics than I am. Take for instance the timer relay I'm wiring. It's a simple DC circuit but the wiring diagram included with the relay means almost nothing to me. It's kind of funny because I can read the 107 page wiring diagram for a 2 million dollar German press that has an electrical cabinet bigger than my kitchen but I cant make sense of the drawings for a simple 24 volt alarm relay. Thanks again for your help, I hope I can lean on you again in the future. Mel |

Hi Dadvin, I've no connection with CircuitLab, I'm just an ordinary Joe who logs in now and then, so it's not 'my' textbook, alas. Yes, I find relay circuits difficult, too. Keep posting! mike |
