Take all the Power of the Taralist Series Relay Controllers
...add a Digi Wireless 802.15.4 Compliant Interface:
Time Activated Control is Effortless!
It works like this. Plug our Wireless 802.15.4 modem into the USB Port of your computer. The modem will mount as a COM port on your PC. Open the COM port and start sending data to the modem. The modem will forward your data to all Wireless 802.15.4 compliant devices within range (it is also possible to speak to a specific device when other controllers are in range). Modem descriptions are at the bottom of the page and can be purchased at checkout of this Taralist board.
The Taralist series Time Activated Relay Controllers are unlike any other relay timer in the world. The Taralist series have an integrated battery backed Real Time Clock with memory that allows users to control relays based on a time schedule. Use your computer to setup the time schedule and store your schedule into the Taralist controller. Once stored, the Taralist does not require a computer, and will activate relays according to a schedule that can be as simple or as complex as your application requires.
Override functions are also supported. So if the normal schedule activates a light during weekdays, but you don't want the light to come on during holidays, simply program your holiday schedule to prevent the light from activating according to your normal schedule.
Daylight Savings Time is also supported, and is FULLY CUSTOMIZEABLE. As we all know, DST laws change periodically, but the Taralist series allow you to change the year and date of all DST events (we have programmed the US dates until 2030).
Taralist controllers allow you to build and save your time schedule as a file on your computer, you can comment your schedule and control which events are active and inactive. We encourage you to keep your schedule file in a safe place. Once you have perfected your file, you can store the time schedule into as many Taralist controllers as you could ever need.
Clock Accuracy is of paramount importance to us. Like most clocks, time drift is a reality that must be considered. The Taralist clock has some special features to help keep the time accurate. We have included time compensation functions that allow you to automatically adjust the clock forward or back (by up to 15 seconds) each day of the week. For instance, you may find the Taralist keeps better time if it automatically advances the clock 1 second each day of the week. Or you may find that you need to subtract 5 seconds from the clock 1 day per week. Adjustable time compensation will help keep your clock accurate (though it is always a good idea to check on the clock periodically).
When the current time matches the time of the event stored in your controller, you can activate or deactivate a single relay, a group of relays, or all 256 relays. You can also set the relays to Computer control or Taralist control (this is perfect for holiday override. A computer may be used to activate/deactivate relays at any time. The computer will override the time schedule. The computer can also return control of the relays back to the Taralist controller, or the Taralist controller can be set to automatically take back control of relays at a specific time.
The Midnight Backup Buffer is a special feature we developed to help keep track of which relays should be activated in the event power is lost. Every night at midnight, the current status of all relays is stored in non-volatile memory. If power is lost, the Taralist will load the status of the relays from memory. Next, the Taralist will calculate all events from midnight to the current time to determine if any relays need to be activated or deactivated. Finally, the Taralist will refresh all relays and will be ready for normal operation.
Boot up time of a Taralist controller is less than 1 second. The CPU on the Taralist controller operates at 64 MHz and is capable of processing 2000 events in 17ms. Taralist controllers may be configured wirelessly or through the USB port using the NCD Configuration Utility. A computer may take control of a Taralist controller and control relays by sending only a few bytes of data (using Wireless or USB communications). The Taralist controller requires power at Midnight of each night for proper operation of the Backup buffer. A very small rechargeable Lithium battery is permanently soldered to the controller; the charge rate of this battery is programmable from the NCD Configuration utility. When connected to the USB port of your computer, the Taralist controller must have power to prevent excessive time drift. The Midnight Backup Buffer may be edited using the NCD Configuration Utility. Time schedule events cannot be processed without power, battery backup is used to keep time only.
