TC-18 Scalable Based Controller

Additional Information


Scalable Time Based Controller

ELTEC has been a leading provider of programmable time clocks used primarily in the traffic industry to control flashing beacons in school zones. Like the NTC-17E that precedes it, the TC-18 has 1 or 2 separately programmable relay outputs. It also includes an integral DC flasher. Complete programming from a keypad with easy to follow ‘common sense wording’ on the LCD screen allows on site testing and programming updates/changes.

The scalable TC-18 is easily upgraded to a TC-3000 IP addressable network time clock. The printed circuit board includes a socket to facilitate the addition of a 900 MHz spread spectrum radio. Upgrading is literally a snap! With the addition of the plug-in radio and an antenna, the TC-18 is capable of receiving programming from a computer through a gateway via spread spectrum radio.

The TC-18 provides a cost-effective solution wit minimal initial investment when updating existing clocks or new installations. Positioning for the future is now a reality. The TC-18 operates on either 120VAC or 12 VDC (solar).

The optional Windows based DLPRO 18 software was developed for intuitive navigation. Each window uses virtual graphics with drop-down calendars and rime tools with easy to understand programming screens.

ELTEC’s DLPRO 18 software was developed for easy navigation. Each window uses virtual graphics with drop-down calendars and time tools (no commands) with straight forward programming screens. Software updates are emailed. The firmware is upgradable via the USB port. It runs on Windows 2000, XP, Vista, 7 and 8 operating systems.

The DLPRO 18 software kit consists of a CD, user manual, and a six foot USB cable for program transfer from computer to clock.
