Digital slave clocks

Digital slave clocks from Yantai Xinghe Clock Co., Ltd. are synchronized time displays designed to receive signals from a central master clock system via NTP, GPS, or infrared protocols. Each unit features a high-visibility LED display with a minimum character height of 50 mm, ensuring readability from distances up to 15 meters. The clocks operate on 24V DC or 110-240V AC input and include automatic daylight saving adjustment, with a time accuracy of ±1 second per month when synced.

These units are built with industrial-grade ABS and polycarbonate housings rated IP54 for dust and splash resistance, suitable for continuous operation in environments with ambient temperatures from -10°C to 50°C. The internal circuitry uses surface-mount components with thermal management designed for 24/7 reliability. While the listing does not specify exact compliance standards, these clocks align with typical industry practices for synchronized time systems in public infrastructure, such as those used in schools and hospitals across Asia and Europe.

Buyers commonly deploy these clocks in educational campuses, hospital corridors, manufacturing control rooms, and transportation hubs where synchronized time is critical for operations. The supplier offers packaging in cartons of 10 or 25 units, with foam inserts and anti-static padding. Trade terms such as FOB Yantai or CIF destination are available, but the exact minimum order quantity and lead time require direct confirmation with the supplier.
