Smart Relay contains a bi-stable RT424F05 relay and uses power only when channels are switching; at all other times it consumes less than 0.5 mA. It can switch 7..28V DC loads with continuous current up to 10A and peak current of 20A (4 seconds, 10% duty rate). To switch between channels, you should cycle the power in one second. If you need to have one load constantly on and one should also be on after the fast cycling of the power, just connect the first load to the incoming power terminals and the second load to channel 2.
