BeagleBone Black Relay Module

This is the first time I write here. I’m from Spain, so firstly sorry for my bad english :smiley:

We are connecting a BBB with a 5v 8-relay module, with the pins 66,67,68,69,45,44,23,26, and pin p9_01 for gnd and P9_05 for 5V

We have two problems. When the system start, the relay #1 goes on, and 3 minutes later, the relay #1 goes off.
The second problem comes when we halt the system. When we do this action, all the relays goes on.

We don’t know what’s happening. We are trying all we know to solve this.

Please, help us.

Best Regards

unless your using level translators your going to fry your BBB
BBB has 3.3v I/O
