It is capable of controlling an electrical circuit using normally open (NO) contacts in which the contact remains open when the relay is not energized or normally closed (NC) contacts in which the contact remains closed when the relay is not energized. In both cases, energizing the interface relay will allow electrical current to be conduction through the relay coil, which in turn will change the state of its contacts. ????
