I've searched the forums for a 240V iot for my Oneida Dust Collector system with no luck. I am wondering if this item I found on Amazon via Google searches: KNACRO 1-Channel DC 5V 30A Relay Module Control Board Optocoupler Isolation High Low Trigger (5V, 1-Channel) might work with my Black Box Controller? I just purchased the Openbuilds IOT, but would like to control my 240V dust collector with the BBC as well. Any CNC electricians in this forum that can answer this one. Thanks.
