Wireless with Built-In Real Time Clock
Wirelessly Configure Schedule with a Computer
Once Configured the Computer is No Longer Needed!
Board Triggers Relay Based on Time Schedule You Configure
The Tarlist controller's time schedule must be configured using a computer and the included Base Station Software. Once configured, a Taralist will operate without a computer. By choosing the 802.15.4 wireless version you will communicate to the board wirelessly through a modem connected to the USB port of your computer. The wireless option is perfect for applications where the board may be mounted where it's difficult to reach. Wireless will allow you to access the board to make time configuration changes or to take manual control of the board. At any time, a computer may monitor the Taralist board, Trigger Events, Activate Relays, or Change schedules. A computer can take over a Taralist or a Taralist can operate autonomously (without a computer).
About 802.15.4 Wireless
802.15.4 is not one of the most widely known wireless technologies but it is easy to setup and use, and vey reliable. You will need a 802.15.4 modem that plugs into your USB port of your computer to talk any number of 802.15.4 relays with a standard range of 300' and up to 1 mile. You can choose the distance of the module installed at checkout.!
802.15.4 Wireless Modules
This board is equipped with a 802.15.4 Module. The 802.15.4 communications module adds wireless communications to the board. The 802.15.4 module is powered from the board. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type transformer at checkout. Click the following link for a spec sheet on the XBeeŽ Multipoint RF Modules
As with any wireless technologies, for optimal performance it needs to be line-of-sight. In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all. Select the External Antenna option to provide better range especially when controller will be mounted in an enclosure or behind a wall or obstruction.
External Antenna Option
The External Antenna option is available with the 300' and 1-mile range modules and has a short pig tail that connects to a button on the 802.15.4 external module. Please note that the internal antenna modules (shown above) have antennas that are about an inch long and integrated into the module. The external antenna cannot be used on an internal antenna module or added after purchase. Prices shown are with the 300' internal antenna option.
802.15.4 Wireless Modem
Plug the XBP24-AUI-EXT_ZIGMO 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). Mounting slots on the modem make it easy to attach to a wall to allow for line-of-site operation. The modem is also available at checkout. 802.15.4 Modem
Take Manual Control of Taralist
At any time, a computer may monitor the Taralist Controller to read the status of the relays, activate relays, or change configuration settings using Base Station Software. This USB version will allow access to the board as long as it is still connected to the USB port of
your computer. A computer can take over the Taralist or the Taralist can operate autonomously (without a computer). The Taralist Configuration Utility is part of Base Station software and this is a free download.
Once the Taralist is configured, it will run through the list of events stored in its on board memory every second to look for a match with the current time. If a match with the current time and a configured event is discovered, it will execute the event.
There are 2 possible ways to control the relays on a Taralist Series controller.
- A Relay can be Directly Controlled by a time schedule.
- A Relay can be controlled from a computer through a RS-232 connection. A computer can take control of any or all relays on a Taralist controller at any time. Once taken over, the Taralist logic will not be able to switch a relay. The computer MUST return control of the relay back to the Taralist Logic for standalone operation.
Who's Qualified to Use the Taralist Series?
Some computer skills required. The Taralist Relays do not require programming, simply configure the device with the included Base Station Software. While programming is not required and simple functions can be done rather easily with basic computer skills, complex events can be configured which will require some understanding and patience.
Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of USB devices, customers may experience loss of communications until the device is reconnected to the USB port. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video
SPDT Relay Controller
This device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings over to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position. For more information on selecting the correct relay amperage for your application see Choosing a Proper Amperage
Integrated Real Time Clock
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.
The Taralist can be configured with a new time schedule after installation using wireless communications to your computer Optionally, the Taralist may be configured using the USB port of your computer (you may change or upgrade communication modules at any time).
Time Schedule Events & How They Work
Events are scheduled times when a relay or group of relays are turned on or off. They are defined by the user first by time: Year, Month, Day of Month, Day of week, Hour, Minute, and Second. By having these options you have the ability of switching relays on or off at very specific times. Activate relays only when the day is Monday, activate relays when the day is Monday and the Year is 2020, activate relays when the day is Monday, the year is 2020 at 9:44:21 AM. They are also defined by how they control the relays, whether they turn a relay or group of relays on or off. You can add up to 999 Events to the list.
Program Multiple Schedules
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.
Setting Controller's Time
By default the Time Relay controller does not know what time it is so this must be defined. The only way of doing this is from the Configuration Utility. Once your controller is connected to the computer and the Configuration Utility is launched the first thing to do is tell the Time Relay Controller what time it is. You may do this manually or you can Sync the time with your PC. This is done using the window below in the Con-figuration utility. The user can do this by simply clicking the Sync Time with PC Time button or by filling in the Year, Month, Day, Week Day, Hour, Minute, Second parameters and then clicking the Set Time Manually button.
Clock Accuracy - Adjustable Time Compensation
Clock Accuracy is of paramount importance. 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.
Time Relay Computer Control
The Time Relay series controllers have some amazing abilities when it comes to making decisions on their own based on the events you configure into them, but you can take control of the relays at any time from a computer as long as communications are established between your computer and the Time Relay device.
The interface elements shown at right allow a computer to take over control of any relay and force the relays to a On or Off state. You may also turn all relays on or off using the all relays on and all relays off buttons. You can also read the status of relays by clicking the Read Relay 1-8 Status. The Status of the relay will be shown to the right of the button. The slider at the top of the screen allows you to select with bank of relays these commands are directed to. You may attach up to 32 banks or 256 Relays.
Power Loss Backup Buffer
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.
We've looked at the interface and the configuration now let's take a look at the board design itself. The Taralist series controllers are machine manufactured for a highly accurate and reliable design. Fully tested before they leave the production facility each Taralist controller is ready to stand up to rigorous demands from heat, cold or vibration. The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions. Take it from us, these controllers will hold up!
Break-A-Way Tabs for a Smaller Design
The Taralist relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure. Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.
Add Relays as Your Needs Grow
The Taralist series controllers are expandable up to 256 total relays. The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay. Expansion boards can be added until you reach 256 total relays. The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.
This board is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.

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.
