UPB UMI Schematic/parts list

Hello,
 
Does anyone have a schematic/parts list for the UMI-32? I have close to 20 of them, but one has a defective SSR. Cannot read the device number on the relay.
 
Thanks,

I've never seen a schematic for any UPB device. Seems to me that those would be kept confidential.

SSR's use such little current, it shouldn't be difficult to find a replacement component that matches the output/switching current rating.
 
Interesting Stuff. A lot of information on cloning site, especially if you are having issues.
 
I was able to source the SSR directly from China for about a buck apiece including shipping. I had a relay protection diode short and draw current through the ssr and frying it. A 2 cent componet taking out  a $100 device. Saved the relay though.
 
Thanks for the info.
 
Good news radiodyne!
 
Let us know how it works for you.
 
Personally here have not used a UMI-32.
 
How are you using your 20 UMI-32's?
 
Here I can see here using them for switching on off my DC LED zoned outdoor lighting. 
 
I am using one UPB relay today to shut off a few DIN mounted power supplies.  It would be nicer to get some more granular control over these power supplies.
