Choosing a Time Activated Board

Taralist controllers are stand-alone time-controlled relay boards with an onboard real-time clock.
They're perfect when you want a schedule that runs all by itself - no computer required after setup.

Looking for a reliable time activated relay? These Taralist controllers offer simple, time-based relay control for switching school bells, pumps, gates, displays and more.

Time Activated Relay Controllers (Taralist Series)

Taralist Time Activated Relay Controllers make scheduling easy. Each board includes an integrated real-time clock, so your relays can follow a precise schedule - day, hour, minute, second - without needing a computer connected 24/7.
Once you create your schedule in Base Station Software and upload it to the board, you're done. The controller handles the rest automatically.

Why Choose Taralist?

Taralist controllers shine in applications where a self-contained, autonomous schedule is all you need. They're a great fit when you want:
  • A set-and-forget schedule that runs without a computer
  • Up to 1,000 programmable events with second-level control
  • Flexible timing: daily, weekly, monthly, yearly, or custom patterns
  • USB, Ethernet, or WiFi connectivity for easy setup
  • The ability to expand up to 256 total relays
Whether you're controlling lights, HVAC cycles, school bells, pumps, gates, displays, or any recurring automation, Taralist gives you powerful timing control with minimal overhead.

How Time Scheduling Works

Taralist controllers allow you to build up to 1,000 events, each defining exactly when a relay should turn on or off.
Events can be scheduled down to the second and include:
  • Year
  • Month
  • Day of Month
  • Day of Week
  • Hour
  • Minute
  • Second
Simple daily on/off cycle or a complex multi-relay timing sequence, the Taralist system gives you full control.

A Quick Note on Clock Drift

Taralist controllers use an onboard hardware clock, and like any standalone clock, it can drift a bit over long periods - usually around one second per day. Most users will never notice it, but if your project depends on super-tight long-term timing (school bells, synchronized lighting, access events, etc.), you'll want to fine-tune it once in a while.

Taralist includes a Built-In Time Compensation feature that lets you correct drift with a quick adjustment. Once it's dialed in, the clock stays remarkably consistent.
⚠️ Best Practice:
Keep Your Timing Tight. Your Taralist clock is already pretty accurate - but if you need near-perfect timing, just use the Time Compensation Tool to fine-tune it. It only takes a moment.
Using a WiFi Taralist? Even better! Automatic NTP Sync updates your clock every day and makes drift virtually disappear.

Choosing the Right Taralist Board

Start by deciding how many relays you need.
Below, you'll find every Taralist model organized by relay count. Select the relay quantity you want, then choose the interface that works best for your installation:
  • USB - Simple, direct PC setup
  • Ethernet - Reliable wired networking
  • WiFi - Flexible wireless communication
Taralist boards support up to 64 onboard relays, and can be expanded to a total of 256 relays using standard expansion options.
💡 Relay Pros ProTip:

Start by choosing how many relays you actually need today. You can always expand Taralist boards later - so there's no need to overbuy upfront.
