duet2 wifi with duex5 and multiple heated beds
-
I'm attempting to get three heated beds connected to our duet controller. I assume that the two leads of the SSR will connect to the terminal block on the right side (E2 Heater - E4 Heater) but does that block supply voltage that is capable of triggering a SSR. The ones we have are rated from 4V to 32V DC.
Any help would be greatly appreciated!

Can you provide some more details about what you'r trying to accomplish?
Are you planning to have the 3 beds independantly controlled or just ganged together?
Are the beds AC or DC?
What kind of SSR is it? Single or multiple?Generally speaking though, the heater outputs on the Duet are capable of switching the SSR input side. They would output at your VIN voltage, which should be in range for your SSR.

@Phaedrux Thanks for looking into this. The printer has three completely separate heated beds. The printer came with three power supplies that contain a TCN4S-24R (small temperature controller) that runs a DC signal to a Fotek KSR-25 DA. The heaters are all set to run off of 220.
Our hope is to have the duet control all three beds individually. My thought was output from the duet to the DC side. That would give us the ability to only have the beds that we need on and then the controller could turn them off once a print finishes. I do have the appropriate thermistors connected and are reading temperatures accurately.

Have you seen this page on connecting bed heaters?

@Phaedrux I have. The problem that I have is I think I've fried my controller. I've been referencing this diagram. I read that in the description here and probably misunderstood that the screw terminals were acting as a relay but in reality probably have enough voltage to run a hotbed or hotend. correct?

If you connected 220V AC to the Duet directly, then very likely yes. The Duet and Duex voltage input (VIN) should be 12V to 24V.

The heater outputs on the Duex are meant for extruder heaters running on 12V to 24V (VIN), and are rated at 6A (though whole board is fused at 7.5A), which would not be enough to run a heated bed directly. As the output on these is VIN (ie 12V-24V) you can connect the heater outputs to the Fotek KSR-25 DA SSR, and control the beds through that. So yes, acting as a relay.

@droftarts We have our printer back up and running. I've learned a bunch through this process. I would like to power the ssr low voltage side with our duex5 heater outputs E2 through E4. I don't see any DC voltage on e4 heater output though when I attempt to set a temperature through the web gui. Should I?
I did measure 24v on the power in connector.

Here is the config file that I'm currently running:
I don't see any heaters defined using the Duex outputs. Am I missing it?

I think I figured it out. I had B0 instead of B1 in my M307 line. Seems to be working as it should now.
