Switchblade2 Posted November 18 Posted November 18 I have a circuit board with a 24 VAC supply and a 24 VAC auxiliary contact that I want to measure if activated or not, 24V or 0V. Is there a way to use a Shelly Plus Uni to do this? Or is it easier with a Shelly Uni? Where to connect the two cables from the auxiliary contact? Quote Translate Revert translation?

Members thgoebel Posted November 18 Members Posted November 18 Circuit diagram with Shelly UNI plus: Power supply alternatively with DC (12 to 24V) or 8 to 24V AC (with an extra diode). Diodes are 1N400x (x from 1 to 7). 1 Quote Translate Revert translation? English (American) Finnish French German Italian Portuguese (European) Spanish
wooly Posted November 19 Posted November 19 even simplier: connect the supply of uni to thw aux contact. then if you can connect, it is on, if you cannot it is off. no need of any other kind of circuit.
