Analog weekly timer PLUG&PLAY W31 Su/Wi, quartz drive 412828

Modern solution for home and industrial automation

The PLUG&PLAY W31 Su/Wi analog weekly timer is a professional device for automatic control of electrical circuits in residential and commercial installations. Thanks to its quartz drive, it ensures extremely precise time control with an accuracy of ±0.2 seconds per day, eliminating the need for frequent setting adjustments.

The device has been designed with simplicity of use in mind - it automatically sets the current time during the first startup and automatically switches between summer/winter time. The single-channel design allows for the control of a single circuit with a maximum load of 17A at 250V AC, making it an ideal solution for lighting, heating, or other electrical receivers.

Precise technology and operational reliability

The heart of the timer is a high-class quartz mechanism, which guarantees stable operation for many years without the need for calibration. A rated autonomy of up to 6 years means that even in the event of power outages, the device will maintain the correct time settings for a very long period.

The weekly program allows for the creation of schedules with a resolution of 120 minutes (the minimum switching time is 240 minutes). Such resolution is more than sufficient for most home and office applications - from controlling outdoor lighting to controlling heating systems in public buildings.

Intuitive operation and advanced programming functions

Device operation has been maximally simplified through the use of physical switching segments that are permanently mounted on the programming dial - there is no risk of accidentally shifting or losing them during installation or maintenance. The manual switch allows for quick switching between ON/AUTO/OFF modes without the need to interfere with the programmed schedules.

An LED diode provides clear information about the current operating mode of the device, and the possibility of sealing the cover protects against unauthorized setting changes - which is particularly important in public or industrial installations.

Safety and installation compatibility

The timer is standardly mounted on a DIN rail, occupying a width of three modules (52.5 × 83 × 60 mm), ensuring compatibility with most electrical distribution boards available on the market. The IP21 protection rating guarantees safe operation in indoor environments at temperatures from -10°C to +55°C.

Potential-free switching contacts allow for the control of circuits of different natures - both resistive receivers (heaters, light bulbs) and inductive ones (motors), while maintaining full galvanic separation between the control and controlled circuits.
