Digital Display
T-SL-300-150-6DN
A 150mm digit is built for one job: staying legible from the far end of a shop floor, a substation yard, or a platform concourse. The T-SL-300-150-6DN takes its time from a single GNSS-disciplined Master Clock over NTP and holds every slave unit on the network to the same second, so a reading taken at one end of the site always matches the one at the other end.
Key Advantages
A practical product foundation for critical infrastructure projects that need dependable hardware and engineering support.
Long-Range Legibility
At 150mm, each digit is readable well beyond the range of a standard 100mm unit, which is what makes this size the right choice for large bays, yards, and high-ceiling halls where operators read the clock from across the room rather than standing next to it.
Multi-Drop Network Architecture
All slave displays share a single common bus, so a new unit joins the existing cable run instead of pulling a fresh home-run back to the Master Clock. This keeps cabling costs predictable as a facility expands its display count over time.
300 Units Across a 1 km Radius
One Master Clock drives up to 300 slave displays spread across a plant area of up to 1 km, which is enough coverage for a full manufacturing campus, a substation complex, or a multi-building site, all referencing the same source of time.
Second-Accurate HH:MM:SS Display
The display refreshes every second in 12-hour or 24-hour HH:MM:SS format, with an HH:MM-only configuration available on request for sites that only need hour and minute reference.
Non-Glare, Wide-Angle Viewing
A red transparent filter overlay widens the usable viewing angle and keeps the display readable under bright ambient lighting, without the washout that affects unfiltered LED panels placed near windows or floodlights.
IP55 Weather-Proof as Standard
The enclosure carries IP55 protection out of the box, with an IP66 outdoor variant available for units mounted on yards, platforms, or exposed structural steel where dust and wash-down resistance matter more.
Fault-Isolated by Design
Because each slave unit operates independently off the shared bus, the failure of one display has no effect on the time shown by any other unit on the network, so a single faulty clock never becomes a site-wide outage.
Wall, Panel, or Table-Top Mounting
The diecast PVC and aluminium housing supports wall, panel, or table-top mounting, which lets the same unit serve a control room wall, an equipment panel, or a reception desk without a different enclosure for each case.
Applications
The 150mm format is a deliberate choice for sites where the viewing distance is long enough that a smaller digit would stop being readable.
