## Summary description

FF PCZ-525.4 is a programmable astronomical time controller for DIN-rail mounting. It provides a single channel with 1 NO/NC contact rated 16 A and operates on 24–264 V AC/DC. Features include astronomic scheduling, an adjustable night break, and NFC-based programming for easy configuration. Suitable for lighting, shutters, and automated building schedules.

## Long description

FF PCZ-525.4 is a programmable astronomical time controller designed for DIN-rail installation. It offers a single switching channel with one changeover contact (configurable as NO or NC) rated for 16 A and accepts supply voltages from 24 to 264 V AC/DC. The device supports astronomical scheduling tied to sunrise and sunset, an adjustable night break function, and NFC-based programming for off-line configuration using a compatible mobile app or programmer. It is intended for automation of lighting, shutters and other time-dependent building systems.
Advantages
The controller combines precise astronomic calculations with manual offset adjustments, allowing schedules to follow natural light cycles while accommodating local preferences. NFC programming simplifies setup and changes without direct wiring, and the DIN-rail form factor enables compact integration into distribution boards. A single robust 16 A contact covers common lighting and motorized-shutter loads, while wide input voltage compatibility supports diverse electrical systems.
Suitable for
Outdoor and indoor lighting control based on sunrise/sunset
Automated window shutters and blinds
Time-based control of signage and facade illumination
Building automation tasks requiring a single switching channel with astronomical timing
Key specifications
Single switching channel with one changeover contact (configurable NO/NC)
Contact current rating: 16 A
Supply voltage range: 24–264 V AC/DC
Astronomical scheduling tied to sunrise and sunset with adjustable offsets
Night break function with adjustable duration and timing
NFC-based programming for configuration and schedule upload
DIN-rail mounting for distribution board installation
How to use
Mount the controller on a standard DIN-rail inside the electrical enclosure and connect the supply and load according to the wiring diagram. Set the contact mode to NO or NC as required by the load. Use the NFC programming interface with a compatible mobile device or programmer to enter geographic location or to set fixed times, apply offsets to sunrise/sunset events, and enable the night break function. After uploading the schedule, verify correct operation by observing scheduled switching and adjust offsets or night break duration as needed.
Usage recommendations
For reliable operation, ensure correct wiring and secure DIN-rail mounting; set the geographic coordinates or local time zone accurately when using astronomic scheduling. Verify that the connected load does not exceed the 16 A contact rating and, where inductive or motor loads are present, consider appropriate protective devices or inrush current measures. Perform test cycles after configuration and periodically review schedules when daylight saving time or seasonal changes occur.
