One network, one day count
Every slave display pulls its day value from the same Master Clock over a shared multi-drop bus, so there is no manual resetting and no drift between units scattered across a site.
Digital Display
NTP Day Display 100mm
T-SL-300-100-3DN
The NTP Day Display 100mm (T-SL-300-100-3DN) is a GPS referenced digital day counter built for facilities that need one dependable day reference across every building on site. Instead of running on its own internal clock, the display takes its signal from a centralised Master Clock over a standard NTP network, so every unit on the plant counts the same day at the same second. The 100mm red dot matrix digits are sized for easy reading from a distance, whether the unit sits above a control room door, inside a switchyard, or along a production line where date based tracking matters. Because each display works independently once it receives the network signal, a fault on one unit never interrupts the rest of the installation.
NTP signal input over CAT 6 or fibre optic cable
Up to 300 slave displays on a single Master Clock
IP55 weatherproof enclosure as standard, IP66 available for outdoor use
Universal 90 to 260V AC/DC power input
Key Advantages
Why plants choose the 100mm day display
A practical product foundation for critical infrastructure projects that need dependable hardware and engineering support.
Scales to 300 displays per site
A single Master Clock can drive up to 300 of these day displays across a plant footprint of roughly one kilometre in radius, which covers most industrial campuses without a second controller.
Dedicated day format readout
The three digit display is purpose built to show the day count on its own, keeping the readout simple and legible rather than crowding a small panel with a full date or time string.
100mm digits built for distance
Red dot matrix LEDs at 100mm character height stay readable well across a shop floor or control room, even under bright ambient light.
Wide angle, non glare viewing
A red transparent filter widens the usable viewing angle and cuts glare, so the display reads clearly whether someone is standing directly in front of it or approaching from the side.
IP55 protection as standard
The enclosure is rated IP55 out of the box, with an IP66 outdoor variant available for units mounted in exposed yards or open process areas.
No single point of failure
If one slave unit loses power or develops a fault, the remaining displays on the network keep counting without interruption, which matters on sites where the day reference feeds safety or compliance records.
