Relay contact is closed when a device power is off
Posted: 17 May 2022, 05:11
Hi,
I'm developing on RevPi connect+ 32GB.
I want to use a relay at the connector X2 as a make relay like below.
Device power-off: relay Open
Device power-on: relay Close
However, the relay acts as below
Device power-off: relay Close
Device power-on: relay Close
I can open the relay via the status byte RevPiLED but I can't change the relay state when power off.
How can I change the relay settings?
