Product Description and Application

The NDC 57/4 R L20 12DC RS485 series digital LED wall clocks are electronic devices which primarily display the current time and date information, but 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 with an IR remote control, via USB or RS485 connection with PC and special software application NDC_config. The RS485 serial bus interface with Modbus RTU communication protocol allows the clock to be built into a unified time system and synchronized with other clocks in the network, or the master clock. 

During its construction the maximum emphasis was placed on high functional reliability and aesthetic appearance. High-brightness 7-segment LED modules and a gray color tinted 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, power supply adapter 230VAC / 12VDC and installation instructions.
