PULSAR DPM DT16 Analog Time Switch with Twilight Sensor, 16A, 230V, IP20/IP65

Electricians and facility managers often need reliable control of lighting in outdoor areas, stairwells, or corridors. The PULSAR DPM DT16 analog time switch with twilight sensor offers a straightforward solution: it combines a mechanical 24-hour timer with an adjustable light sensor, so lights can turn on at dusk and off at a preset time, or follow a daily schedule regardless of ambient light. Installation is simple on a wall or DIN rail, and the sensor with 1 m cable can be placed where it best detects daylight.

Why choose it

The DPM DT16 stands out for its versatility: you can use it purely as a timer to switch lights on and off at fixed times, purely as a twilight switch to react to daylight, or combine both functions for maximum energy savings. The mechanical clock requires no battery and keeps working even after power outages. The adjustable twilight threshold and delay prevent false triggering from car headlights or brief clouds. With a 16 A resistive rating, it can handle large lighting loads directly without an additional contactor.

Ideal use cases

• Outdoor lighting for building entrances, parking lots, and gardens
• Stairwell and corridor lighting in apartment blocks or offices
• Shop window illumination that follows daylight
• Signage and advertising lighting
• Greenhouse or livestock lighting with day/night cycle

Good to know

The sensor is rated IP65, so it can be mounted outdoors in a sheltered location, while the main unit should be installed indoors or in a weatherproof enclosure (IP20). The mechanical switching segments are set using the dial; each segment corresponds to 15 minutes. The unit does not include a battery, and the clock is powered directly from the mains. For inductive loads such as fluorescent ballasts or LED drivers, keep the total current below 2 A or use a relay.
