CLDNTD12 NTP Analog Digital Clock
The CLDNTD12 combines a traditional analogue dial (rendered in LEDs for the seconds) with a digital NTP-driven display for hours and minutes.
Both time indications remain exactly aligned and synchronise to the same NTP source. A familiar classic look in a meeting room or foyer, with the IT reliability of network time. Ideal for those who want to keep the legibility of an analogue clock without mechanical hardware and without separate maintenance.

- Adjustable brightness levels
- Reading distance: 30 meters
- Wall-mount bracket
Physical
- Anti-glare lens prevents reflections from artificial light
- Black powder-coated steel chassis
- Size: 12w x 12h x 2.1d in (30.5w x 30.5h x 5.3d cm)
- Weight: 5.5 lbs ( 2.5 kg )
- Black powder-coated steel chassis
Operating Parameters
- Temperature: 0 to 60°C
- Humidity: Up to 90% (non-condensing)

Frequently asked questions
Is the CLDNTD12 also available in a round version?
Yes. The CLDRNTD12 is the round variant with the same NTP functionality and analogue-digital display. The only difference is the case shape.
What colour LEDs does the digital section use?
Available in red, green, blue or amber. The analogue ring with second-LEDs follows the same colour. Specify your choice at order time; the colour cannot be changed afterwards (unlike the LUX26).
Does this clock also work on PoE?
Yes, the CLDNTD12 supports PoE per IEEE 802.3af. The alternative is 24 VDC from the universal power adapter that is supplied as standard; the clock has no built-in mains inlet. Choose PoE when you want a single cable to the clock, or when there is no room to mount the adapter at the clock.
What is the lead time for this product?
Standard lead time is 8-10 weeks from Masterclock USA. Daylight bv stocks the most common references in Ghent. Contact us for current availability and any rush options.
