Hi,

I am looking for any suggestion on what relay would be compatible with the webcontrol8 controller.

I have found some optically isolated Solid State Relays (SSRs) but would like a recomadation on ones that have been used with the webcontrol8.

Thanks

Gary

Gary,

I have been using these to drive loads close to the web controller and to power other a/c relays far away from the controller over low voltage wire. They are cheap and have no problem over the years.

I to have used these inexpensive boards for a long time as well, longer than 10 years in service. Some have opto couplers others used a transistor to switch each relay on either are fine..

Thanks @EricBarish and @TJF1960 ,

I couldn't fine them from the picture. I was wondering if you could provide a part number and where to buy.

Thanks

Gary

ebay.

If memory serves, webcontrol allows something like 20ma max per channel and 50ma total for all 8 at any time. I haven't really read through the linked item on ebay, but it looks like they are saying it pulls 5ma at 5v to trigger any one relay, so if I am reading that correctly, this would do the trick. Theoretically the opto isolated relays also greatly reduce risk of damaging the web control board should something go awry with the switched load on the main relay. You have to provide a separate power supply for the relay board which is where the power comes to drive the actual relay.

Thanks @apostolakisl ,

Found them.
