Compact 14mm character size
Sized for the sightline it actually serves. A 14mm character is easy to read from a few feet away, which is the normal viewing distance on a panel or a rack, so the display does not need to be oversized to be useful.
Digital Display
NTP Time Display 14mm
T-SL-300-014-6DN
The NTP Time Display 14mm is a panel mount slave clock built for places where a full size wall display does not fit. At 125 mm wide and 33 mm tall, it sits comfortably on a control panel, a 19 inch rack, or an instrumentation desk, while still pulling GPS traceable time from your network over a standard NTP feed. Each unit reads time to the second in HH:MM:SS format, stays in step with every other display on the same Master Clock, and keeps running even if a neighbouring unit on the network goes offline.
NTP input over CAT 6 or Fibre Optic
Up to 300 slave units on a single Master Clock
IP55 weatherproof as standard, IP66 available for outdoor use
Compact Type C powered design, ready for panel or rack mounting
Key Advantages
Built for Panels, Racks, and Close Range Viewing
The 14mm format is not a smaller version of a wall clock. It is sized on purpose for the distance operators actually sit from it, whether that is a control panel door, a rack unit, or a desk-mounted instrument cluster.
Multi-drop network architecture
Every display on the network shares one common bus, so adding a unit to an existing installation does not mean running a dedicated cable back to the Master Clock for each new point.
Up to 300 units per Master Clock
A single Master Clock can drive up to 300 slave displays across a plant area of up to 1 km radius, which covers most industrial buildings, campuses, and multi-floor facilities without a second master.
HH:MM:SS display, 12 or 24 hour
Operators can set 12 hour or 24 hour format depending on site convention, with seconds shown at all times for processes where that level of detail matters.
Non-glare, wide angle red LED
A red transparent filter overlay keeps the digits legible under panel lighting and from a side angle, without the glare that plain LED segments can produce under bright fixtures.
IP55 weatherproof as standard
The enclosure is rated IP55 out of the box, which covers dust and light moisture on a typical shop floor, with an IP66 option for units going into outdoor enclosures or exposed yards.
Fault isolated network
If one slave display is powered down, disconnected, or faulty, the rest of the network keeps showing synchronised time. A single point of failure does not become a site wide outage.
Type C powered
The unit runs on a 5V, 2A Type C supply, the same connector format used across most modern panel and rack electronics, which keeps spares and replacement cabling simple to source.
