National Time & Signal

The WeM Web-Enable module upgrades the MC100/MC100-RM master clock to a web-based interface. This provides an easy-to-use interface to configure auxiliary devices such as bells, chimes, tones, or even clocks; it also ensures that your bells and clocks are precisely synchronized.

The WeM operates on any TCP/IP-based Ethernet network, and automatically synchronizes the clock system with any standard NTP or SNTP time server or with the official United States atomic clock time source in Boulder, Colorado. The WeM automatically corrects for daylight savings time and power outages.

The WeM can be configured, programmed, and monitored from any PC on the LAN network through a standard browser interface and a dedicated PC is not required during normal operation. The WeM-MC100 module mounts directly into the standard MC100 wall box.

The MC100 is a microprocessor based clock and auxiliary circuit controller capable of synchronizing both digital and analog secondary clocks. The MC100 provides automatic corrections for power outages as well as programmed events such as daylight savings. Powered by a 120VAC supply, the MC100 utilizes a 10 year lithium battery for backup during power outages. A user-selectable time base allows the master clock to either monitor the power-line frequency, internal crystal oscillator as well as an optional GPS or LAN interface to provide the most accurate time keeping. The MC100 comes standard with four circuits which may be used as either clock circuits or auxiliary circuits for tones, bells, and other timed events. Each circuit has an indicating LED and an OFF/AUTO/RESET slide switch for ease of manual control. The wall mount MC100 may be expanded to up to 12 circuits with the addition of EXP-4 circuit expander boards. Programming is easy utilizing a backlit 32 character liquid crystal display and a 16 button keypad. The multifunction keypad provides single button menu access allowing quick and easy time, schedule, and setup changes. Two level password security may be used to protect technician level settings and programmed events. The MC100 supports three program schedules with up to 200 program entries. Each event duration is programmable from 1 second to over 4 days. Attractive neutral Powder Gray finish with Night Blue graphic overlay complete with label pockets for custom circuit legends.

More Details

Being ecologically friendly does not mean you have to sacrifice features. National Time is proud to introduce the industry’s lowest power consuming digital clock with features beyond those of other manufacturers. This microprocessor based secondary clock has the intelligence to adapt to the system on which it is installed. Whether it is a 3-wire synchronous system with 58th minute correction or hourly correction, a 4-wire system with AC run and DC reset, a two wire system with on-demand actual time reset, or one you haven’t seen for years... this is the clock for you. Right out of the box, this clock can distinguish and accept the most popular reset formats.

Having the industry’s lowest power consumption means more clocks can be powered from a single power supply, longer wire distances and less expensive smaller wire gauges. Compare competitor’s currents at 12 to 15 times our current! This adds up to savings to the installer as well as the owner with lower operating costs. A battery-less backup timekeeping circuit is capable of surviving power outages over 10 days which alleviates long reset cycles even when operating on existing synchronous systems. Stand-alone operation without a master clock is also made possible using the included time setting buttons. 12 hour or 24 hour time format is selectable at each clock.

This premium series also offers National Time’s exclusive automatic dim feature that decreases the brightness to compensate for low ambient light levels associated with artistic and video productions. This not only provides a pleasant brightness level, but also saves energy during nighttime hours. Nine brightness levels may be selected to satisfy the brightest locations. Class change count-down timer function is also supported. A popular option in K-12 schools. When operating on a two wire clock system, the reset input can be used to initiate a count-down timer and the duration can be individually set at each clock. (Optional beeper available, contact factory.) Alternately, a count-up timer function can be selected and will increment while the reset input is active for other custom applications.

Units can be powered by either 24VAC or 24VDC and have attractive 4" or 2.25" high visibility, wide-bar digits. 6-Digit versions also available, see DLU225-6 and DLU400-6. Compatible with 120VAC powered systems when the appropriate 24VAC transformer is mounted at each clock or double face unit. The durable steel housing, plug-in connectors and universal mounting plate simplify installation. An optional low profile surface box allows for surface mounted conduit entry. Powder gray finish standard, black and other colors upon request.
