BRG Alpha Digital Clocks — Five Dot Matrix LED Clocks That Show More Than Just the Time
By BRG Precision Products | October 30, 2026 | Synchronized Clocks • Digital Clocks
Most digital clocks use bar-segment LEDs — the familiar “figure 8” digits. They’re bright and easy to read, but they can only show numbers. BRG Alpha Digital Clocks use dot matrix LEDs instead. Because every character is built from a grid of individual LEDs, an alpha clock can display letters as well as numbers — so it can show the day of the week, the month by name, or the full date right alongside the time.
BRG offers five Alpha Digital Clock models, and every one is available in six versions: Stand-Alone, DuraTime Wi-Fi, DuraTime 2.4 GHz Wireless, Ethernet, PoE and DuraTime High Precision.
The Five Alpha Digital Clocks
| Model | Display | Size (H × W × D) | Good For |
|---|---|---|---|
| AC200501 | One line, 5 characters, 2.0″ dot matrix | 6.125″ × 11.88″ × 2.25″ | Large, simple time display |
| AC121001 | One line, 10 characters, 1.2″ dot matrix | 6.125″ × 11.88″ × 2.25″ | Time with seconds, or time and a short message |
| AC121501 | One line, 15 characters, 1.2″ dot matrix | 6.125″ × 16.88″ × 2.25″ | Longer date formats on a single line |
| AC121002 | Two lines of 10 characters (20 total), 1.2″ dot matrix | 6.125″ × 11.88″ × 2.25″ | Time on one line, date or day on the other |
| AC201202 | 2.0″ 5-character time over a 1.2″ 10-character date | 6.125″ × 11.88″ × 2.25″ | A true digital calendar clock — large time, full date below |
All five models have a 50 ft. viewing distance and come in a black polycarbonate frame.
Six Ways to Keep Time
Every alpha model is available in each of BRG’s timekeeping versions. The model number starts with the version prefix — for example, SAAC201202 is the Stand-Alone version, ENAC201202 is the Ethernet version and PEAC201202 is the PoE version.
| Version | How It Keeps Time |
|---|---|
| Stand-Alone | TCXO oscillator; updates automatically for Daylight Saving Time; no network required |
| DuraTime Wi-Fi | Synchronizes to your NTP server over your existing 2.4 GHz Wi-Fi network |
| DuraTime 2.4 GHz Wireless | Receives time from a DuraTime master clock over BRG’s self-healing wireless network |
| Ethernet | Synchronizes to your NTP server over a wired network connection; AC powered |
| PoE | One Ethernet cable carries both power and synchronized time |
| DuraTime HP | OCXO oscillator, factory synchronized to the U.S. Atomic Clock, accurate to one second over 20 years |
Why Choose an Alpha Clock?
Time and Date in One Place
A calendar clock like the AC201202 replaces a separate clock and date display on the wall. That’s especially useful in hospitals and clinics, where staff charting patient care need both the time and the date at a glance.
Clearer Information
Dot matrix characters can spell out the day of the week and the month, which removes any doubt about whether “10/11” means October 11 or November 10.
User-Changeable Colors
Like all BRG LED digital clocks, the alpha clocks let you change the display color any time you want: Red, Blue, Green, Yellow, Magenta, Cyan or White.
Matches Your Other BRG Clocks
Alpha clocks share the same 6.125″ height as BRG’s 2.5″ and 4″ digital clocks, so they look right when installed on the same system.
Frequently Asked Questions
Q: Which alpha clock should I choose?
If you want the time and the full date together, the two-line AC201202 calendar clock combines a large 2.0″ time display with a date line below it. If you just want big, clear time, choose the AC200501. Call BRG and we’ll help you match the display to your room.
Q: Can I mix alpha clocks with standard digital clocks on the same system?
Yes. For example, PoE alpha clocks and PoE bar-segment clocks can share the same network and time server. Call BRG and we’ll help you plan your system.
Q: Are BRG alpha clocks available on GSA contract?
Yes. Many alpha clock models are available through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct with no authorized third-party resellers.
More than numbers. Time, date and day — in dot matrix LEDs.
