2. انتهى المنتجview

The Eltako S2U12DDX-UC is a 2-channel programmable clock designed for DIN rail mounting. It features two potential-free contacts (1+1) rated at 16 A/250 V AC. This device supports LED lamps up to 600 W and incandescent bulbs up to 2000 W. It includes an Astro function for automatic switching based on sunrise/sunset, an illuminated display, and a power reserve of approximately 7 days without battery.

Thanks to patented Eltako-Duplex (DX) technology, the normally potential-free contacts can switch 230 V AC 50 Hz, significantly reducing wear. This is achieved by connecting the N conductor to terminal (N) and L to 1 (L) and/or 3 (L), resulting in an additional standby loss of only 0.1 W. The use of bistable relays eliminates coil power loss and heating when switched on.

Up to 60 memory locations are freely assignable across the channels. The device includes automatic date and summer/winter time changes.

4. Connect the L conductor to 1 (L) and/or 3 (L) for the respective channels.
5. For centralized control, connect the control input (+A1) for central ON or OFF with priority. The supply and control voltage for central control is 8 to 230 V UC.
6. تأكد من أن جميع التوصيلات آمنة وصحيحة قبل إعادة تشغيل الطاقة.

3.2. Initial Configuration - Language Setting

After applying power for the first time, the language selection menu will appear.

1. Within 10 seconds of applying power, use the تعيين button to select the desired language (D=German, GB=English, F=French, IT=Italian, ES=Spanish).
2. قم بتأكيد اختيارك باستخدام ملف وضع زر.
3. The display will then show the normal view: weekday, time, day, and month.

ملاحظة حول السرعة: Parameters increase rapidly when the تعيين button is pressed and held. Release and press again for longer to change direction.
