Analog timer PA 352.230, 50Hz, 1 NO contact, 412812

Analog DIN rail time switch

The PA 352 analog time switch is a reliable solution for the automatic control of electrical circuits in domestic and industrial installations. The device provides precise programming of switching in a daily cycle, enabling the automatic switching on and off of lighting, heating, or ventilation according to scheduled hours.

Design and technical parameters

The timer is housed in a standard modular enclosure with a width of 3 modules (52.5 mm), allowing for mounting on a standard TH35 rail. The device has dimensions of 83 × 52.5 × 60 mm and provides an IP20 protection rating, protecting against finger contact and access to solid objects larger than 12 mm.

The control mechanism is based on mains frequency synchronization (50 Hz), without quartz control. The control dial allows for precise switching settings every 15 minutes, with a minimum switching time of 30 minutes. The timer is equipped with a potential-free changeover contact, which allows for the control of circuits with different potentials.

Power supply and switching capabilities

The device is powered by 230V AC ±10% at a frequency of 50 Hz. It provides a switching current of up to 16A at 250V AC, allowing for the control of loads up to 4000W. The timer features 1 switching channel and a manual override function, enabling immediate switching on or off of the circuit regardless of the set program.

Programming functionality

The timer offers full daily programming functionality with the possibility of setting a preliminary switching adjustment. The device does not feature automatic daylight saving time adjustment or weekly/yearly programming—it focuses on simple but effective daily programming. The design allows for the cover to be sealed, protecting against unauthorized setting changes.
