Wireless Synchronized Digital Clock

Masibus Wireless Synchronized Digital Clock, Master Clock MC-2 and Slave Clock DDU-24/44 is a perfect solution for a wide range of applications where accurate, synchronized time is required. It displays parameters like Time and Date.

Wireless Synchronized Digital Clock eliminates wiring and reduces installation cost and also allows a retrofitting of an existing installation in a convenient way. Each clock can work as Slave cum repeater that helps to extend the network range. The Wireless system allows multiple Slave clocks to work on same/multiple frequency range and can retransmit without interfering with other wireless products.

Frequency hopping technology is available for error free communication in case of interference from some wireless device on some particular communication frequency.

Wireless Synchronized Digital Clock System also has two more options of wired RS232 or RS485 Connection other than RF wireless connection to sync with GPS Master Clock.

MC-2 and DDU-24/44 works on Time protocols like (NGTS, NMEA and TFormats) for wired Connection.

The DDU-24/44 has built-in Battery backed RTC which maintains time in case of loss of power and communication break. DDU-24 Slave Clock is specially designed with SS faceplates, Modular wall mounting compatible for Pharma & Clean room requirement. The rugged Mild Steel case with front soft steel makes DDU-24/44 ideal for demanding industrial environments and elegant look. Flush LED display of DDU-24/44 offers a wide angle viewing. DDU-24/44 are available in Flush Mount, Panel Mount & Wall mount versions.

MC-2 Master Clock is designed in ABS Enclosure with Wall Mount or Table Top provision.
