The BV110 is a twin 10A relay with 20A current sensing. This makes it possible to confirm that the device it is connected to is actually switched on.
The device operates from 5V but has current sensing outputs for 5V or 3.3V logic. It can sense positive and negative currents via the M1 or M2 outputs. The output is an analogue voltage. The current sensing IC is an ACS712
The relay is designed as a 2 outlet switch.
The black wires are all common. Power input is via the top and this power can be switched to either one or both of the outputs depending on the control voltage. The current sense will monitor the total power for all of the current flowing
