Hello everyone. Can the onboard relay carry a spindle/router of 230v? I have tried to mark in the picture attached to this thread. Best Regards Stig Lindberg.
We would not recommend using it for Mains AC sorry (as the rest of the board carries low voltage DC, and we did not intend for it to handle AC, no isolation testing etc was spec'ed) it may not be safe You can handle 6A through it - the relay is rated 10A but the connectors are rated 6A.
Many thanks for the quick reply. Sorry for my bad english. The reason I asked was because the company that built the cnc milling machine for me took a 230v spindle of 1050w 4.8A and ran the phase wire through the onboard relay and this resulted in the Blackbox controller kicking me out while running the milling program and shut down up to several times and threw the code Error 9. That's why I first examined my Gcode and nothing unusual was there to see in the Gcode, then I started looking for the connection from the milling machine to the blackbox controller how it was put together. Then I see that the phase wire has been run through the onboard relay, therefore I thought that it did not look quite correct. I have now drawn power to the spindle motor as normal and now they work as they should. Thanks for saving my day and a big possibility that I could have accidentally toasted the blackbox controller. Best Regards Stig Lindberg.
Good catch! Yes that is scary! Please let the company know we do not approve, you can include a link to this thread or ask them to contact us via Submit a ticket if they have any questions The intended use case for the relay is documented here: docs:blackbox:jumper-relay [OpenBuilds Documentation]
Many thanks for the help, I am sending a reference to the company in question so that they do not make the same mistake on other similar customer machines
