## Summary description

The Pollin MROK-16S twilight switch is a reliable light control device designed for DIN rail TH35 mounting. It operates at 230V with a 16A load capacity and features an adjustable sensitivity range of 2 to 50 lux. Equipped with an external SN-16L surface-mounted sensor, this device automatically manages lighting systems based on ambient light levels, making it ideal for energy-efficient outdoor and indoor illumination control.

## Long description

The Pollin MROK-16S twilight switch is a professional-grade light control solution engineered for installation on standard TH35 DIN rails. This device provides automated management of lighting circuits by monitoring ambient light levels through an external SN-16L surface-mounted sensor. With a robust 16A load capacity and a 230V operating voltage, it ensures reliable performance for various lighting applications, helping to optimize energy consumption by activating lights only when natural illumination falls below the set threshold.
Advantages
The primary benefit of this twilight switch is its ability to provide fully automated lighting control, which significantly reduces energy waste by ensuring lights are only active during hours of darkness. The inclusion of an external surface-mounted sensor allows for flexible placement, ensuring the light detection is not influenced by the light source being controlled. Its design for DIN rail mounting simplifies integration into existing electrical distribution boards, while the adjustable sensitivity range provides the flexibility needed to fine-tune operation based on specific environmental conditions.
Suitable for
Automated control of outdoor street or garden lighting
Illumination management for building facades and parking areas
Energy-efficient lighting control in warehouses or industrial facilities
Indoor lighting systems in corridors or stairwells requiring dusk-to-dawn operation
When it may not be suitable
This device is not intended for use in environments where high-frequency switching is required or where the ambient light levels fluctuate rapidly due to artificial sources. It is also not suitable for direct control of high-inductive loads that exceed the 16A rating without the use of an additional contactor.
Key specifications
Operating voltage: 230V AC
Maximum load capacity: 16A
Sensitivity range: 2 to 50 lux
Mounting type: DIN rail TH35
Sensor type: External surface-mounted SN-16L
How to use
Installation should be performed by a qualified electrician in accordance with local safety regulations. The main control unit is snapped onto the TH35 rail within the distribution cabinet. The external SN-16L sensor must be mounted in a location where it can accurately detect natural daylight, away from the direct glare of the lamps it controls. Once wired, the sensitivity threshold can be adjusted using the control dial on the front of the unit to match the desired activation level.
What to consider before purchase
Ensure the total power consumption of the connected lighting does not exceed the 16A limit
Verify that the cable length between the sensor and the control unit is within the manufacturer's recommended limits
Confirm that the installation environment is protected from extreme moisture or direct weather exposure if the main unit is not in a sealed enclosure
Usage recommendations
For optimal performance, ensure the sensor is positioned to face north or in a shaded area to prevent false triggering from direct sunlight or artificial light sources. Regularly clean the sensor lens to maintain accurate light detection.
