This convenient real-time-clock controller turns single AC and DC loads ON and OFF. Use for any light or appliance you wish to turn ON or OFF at a specific time, including cabin lights (to fool possible intruders!) navigation lights, fans, blowers or bilge pumps. Programmable memory is capable of eight independent ON/OFF events. Example: Use one ON event to have a light come on at 7:00 p.m. every day, then use seven different OFF events to turn it OFF at a different time every day. 12V DC.
