MOSFET's has good switching characteristics and is widely used to control almost any DC load. This is a 4 channel MOSFET switch and it use the very popular IRF540 MOSFET. It is perfect for switching DC loads up to 10A. The module is opto-isolated, please note that the GROUND connections are in common so there is not complete isolation. Not a real biggy for DC Loads, but something to be aware of. The module is basically a "Solid-State Relay" for DC. Up to 4 individually controllable loads may be connected to the (+) and (-) switched outputs, all fed from a common power rail. Being a low side switch, when the switch is on, it connects the load (-) terminal to ground.
