The relays are something I found here locally. They are called PLA relays. I use them to switch 240V A/C to 5V DC. Is it only to tell your micro, that certain lines carry 240VAC? Well, I ask, because these relays will consume a considerable amount of power. Looking at the datasheet 64 relays will result in a total heat dissipation of nearly 400W! You can use different methodes for the mains voltage detection. For instance, ultra small mains transformers. Or, perhaps better, opto couplers. Kai |

| Yes, I know but..... | 01/01/70 00:00 | |
| no, they are not "independent of the supply voltag | 01/01/70 00:00 | |
