Product Description and Application

The NDC 100/4 THS R L20 PoE LAN series digital LED wall clocks are electronic devices which display the current time, date, temperature and relative humidity information. It can also be set and used as a stopwatch or countdown, count-up counter/timer.

The clock is especially suitable for use in modern interiors of various public institutions, offices, railway and bus stations, airports, hospitals, shopping centers, banks, production plants and many other places, where its installation provides an aesthetic and practical add-on.

All clock‘s parameters, e.g. time, date, stopwatch, countdown, brightness, the type and duration of displayed information, etc., can be set via LAN connection with PC using Internet web browser and clock‘s embedded application - Web Server.

The clock is equipped with a PoE LAN Ethernet interface, which allows its integration into a unified time system and synchronization with NTP server or other clocks on the network using LAN Ethernet TCP/IP connection with Modbus TCP communication protocol.

During their construction the maximum emphasis was placed on high functional reliability and aesthetic appearance. High-brightness thre7-segment LED modules and a dark cover glass with an anti-reflective coating ensure good readability and a wide viewing angle. The brightness level can be controlled automatically, depending on the ambient lighting conditions, or manually, according to the user's preference.

Installation is easy, the clock is supplied with a wall hanging bracket and installation instructions. In addition, the PoE LAN interface allows the clock to be installed without the need of separate power cables installation because the clock is powered directly from the LAN network (Power over Ethernet).
