Line Powered RF Synchronized Digital Clock (DTC Series)

The TimeCastTM digital clock series has more features that ben- efit your organization than any other. NATSCO’s exclusive au- tomatic dim feature decreases the brightness to compensate for low ambient light levels associated with surgical suites and video productions. This not only provides a pleasant bright- ness level, but also saves energy during nighttime hours. Nine brightness levels may be selected to satisfy the brightest loca- tions. Add a durable metal housing to the long life epoxy filled digit segments and you won’t find better value. Available in both 2.3” and 4” wide bar digits that increase the visibility over clocks of comparable size. 6-Digit versions dis- playing hours, minutes and seconds are also available.

The 24VAC/DC version can leverage easier to install, low voltage, power-limited wiring for less costly installation. The 120V version can use a local 120V circuit. The hard wired version includes a 120/24V transformer that mounts in a stan- dard electrical box. The wall transformer version can plug into a nearby stan- dard 120V outlet. Cases are available in black or grey.

The OLED display behind each clock pro- vides easy setup and diagnosis. Quickly de- termine if the TimeCastTM signal and time data has been received. At a glance, determine the signal strength from the clock back to the base station, last check-in, number of peer clocks within range and other information. User buttons provide menu navigation and setting initial time and date if necessary. Clock settings such as brightness, auto-dim thresholds, time zone and test routines also utilize this easy to understand display.

Unique QR code at each clock directly links to the free NATSCO cloud service. Complete check-in history with signal strength and nearby clock information is displayed as well as product information and trouble shooting assistance.

Plastic Line Power RF Synchronized Analog Clock (TimeCast Series)

The TimeCast™ analog clocks make clock system expansion simple. When battery maintenance is not desired, order the 24V wired version. The 24V version can be powered with 24VAC or 24VDC. These can leverage easier to install low voltage power-limited wiring for less costly installation. For line voltage 120V installations, there is a choice of a hard wired transformer that fits in a standard electrical box or a wall transformer that plugs into a nearby standard outlet. Double face clocks can share a single transformer.

All versions include National Time’s exclusive user display interface to simplify installation and troubleshooting. The 12” clock cases have durable ABS case with shatterproof polycarbonate lens. Cases are available in black or grey. The dials are standard white with black numerals and markers. Contact the factory for custom dials and logos for your school or business.

TimeCast Base Station (TC-BS-WM)

A cost-effective base station is the beginning of your TimeCast™ system. This Power-over-Ethernet (POE) unit is small enough to mount wherever needed. For installations without POE, the unit can be powered with a 5VDC micro USB wall plug.

The easy to understand user interface with 4-line display makes setup a breeze. The LAN connection can use a local or internet SNTP time server to keep accurate time. A battery-less backup system can keep time during outages for over 10 days.

TimeCast™ signals are transmitted to all nearby clocks and is repeated by each clock for complete building coverage. All secondary clock information is gathered by the base station and stored locally or uploaded to the free National Time cloud service.
