When 12v is feed into the receiver's red/black wire, receiver is in standby mode, current draw at 4.7mA, and relay stays in "open" mode. When remote transmitter is depressed, receiver's internal relay then closed, current draws 7mA with no load, and 12V DC is present at the output white+/black- wires. Maximum load to the relay receiver is 20A. When remote transmitter is depressed again, relay return to "open" state, and receiver is back in standby mode and continue to draw 7.5mA from your power supply unless the power is shut down.
