4 Output Cyclical Night/Day Lighting Controller (12Vdc, 4A)

12Vdc, 4 output cyclical Day/Night lighting controller providing a repeating virtual-day simulation effect (Sunrise-Day-Sunset-Night) with user adjustable times. Each output is active at different parts of the virtual day and rated for loads of up to 4 Amps. Suitable for LED strips and incandescent bulbs. Can be used to power a different lighting circuit, providing flexibility for producing virtual day and night scenes in nativity scenes, models, shop displays, etc.

Four x 4 Amp outputs provide control of lighting based on different periods of the day:

• Output A: Daybreak > DAY > Nightfall
• Output B: Nightfall > NIGHT > Daybreak
• Output C: Auxiliary DAY
• Output D: Auxiliary NIGHT
• Operating Cycle and Output State Diagram (See image above)

The Sunrise/Sunset transition time is user adjustable providing a fast or gradual transition in lighting intensity. The length of the Day/Night phases of the day cycle are also user adjustable.

The shortest duration one "day" can be set to is 4 seconds and the longest day duration possible is 8 hours.

The Auxiliary Outputs are active during the respective Day or Night part of the cycle.

The Start Point setting allows selection of the desired initial state (either Daybreak, Day, Nightfall or Night) when power is applied
