While relays are very useful for switching things on and off, for situations where power consumption is to be kept to a minimum, the power used by the relay itself can be a problem – for example where a small LED light is to be switched, the power taken by the relay could be more than the power taken by the light. A Mosfet must be selected to able to drive the required load current. Red LED Power Indicator. Insensitive to positioning. Inspite of, that the coil of the relay is always optimalized for a minimal power consumption, still it is not neglible, especially at relay arrays or at battery powered devices. S2EB-5V. Green LED indicator for each channel. Obviously depending on the relay type some component values might have to be modified, but the method described should work for most DC relays. If you want to externally power the relay itself then make sure to connect the +5 to the Vcc on the relay board and the -lead to the GND on the relay board.
