Digital Display
T-SL-DD-300-100-6DN
Every control room eventually runs into the same small problem. The wall clock shows the time correctly, but the date is left to a desk calendar, a whiteboard, or whatever the operator last remembered to update. Across a large site with several buildings, that gap turns into a dozen different dates on display at once. Sertel's NTP Date Display 100mm removes that gap by pulling its date directly from a GPS disciplined Master Clock over the plant network, so every slave unit, from the gate to the control room to the substation yard, shows the same audit correct date, refreshed automatically, around the clock.
Key Advantages
A practical product foundation for critical infrastructure projects that need dependable hardware and engineering support.
One Master Clock, Hundreds of Displays
A single Master Clock can drive up to 300 slave units wired on one common bus, spread across a plant area of up to 1 kilometre radius. There is no need to run a separate controller to every building or shop floor.
1 km Coverage on a Shared Bus
The multi-drop network architecture lets new displays join an existing bus without rewiring the whole plant, which keeps expansion costs down as a facility grows.
DD:MM:YY and DD:MM:YYYY Formats
The date updates automatically in DD:MM:YY or DD:MM:YYYY format, the convention used across most Indian industrial, defence and infrastructure documentation, so shift logs and inspection records line up without manual correction.
100 mm RED LED Digits
Large 100 mm, 7-segment digits in red stay legible from across a shop floor, substation yard or platform. Character size can be customised where a project calls for something larger or smaller.
Non-Glare, Wide-Angle Visibility
A red transparent filter overlay cuts glare and widens the viewing angle, so the date stays readable under bright overhead lighting or direct sun, not only when viewed head on.
IP55 Weather-Proof as Standard
Every unit ships IP55 rated for dust and splash protection, with an IP66 outdoor variant available for displays mounted at gates, yards or open sheds.
One Faulty Unit Will Not Take Down the Network
Each slave display works independently off the shared bus, so a fault in one unit has no effect on the date shown by any other display on the network.
NTP Synchronisation Over Existing Infrastructure
Signal travels over standard CAT 6 or fibre optic cabling using NTP, so the display can usually be added to infrastructure already in place, without a dedicated signal cable run.
