MDN49 NTP AND IRIG-B Digital Clock 10,2 cm
The MDN49 is the large version in the multi-function MDN range, with 10.2 cm LED digits in red or blue.
Supports NTP, IRIG-B1, CS5 and CS3 input, which makes the unit suitable for large-format time display in installations with multiple protocols. Typical applications: military command centres, broadcast facilities with mixed timing, or legacy IRIG installations adding NTP without removing the old infrastructure.

Frequently asked questions
Why only red and blue?
The MDN49 is a specialised model with smaller production runs than the NTDS46. Red and blue are the most-requested colours in the military and broadcast contexts where this model is typically deployed.
What is the viewing distance of the MDN49?
10.2 cm digits are typically readable up to ~30-40 metres under normal indoor lighting. Suitable for large control rooms, command centres or production halls.
Is there a larger format than the MDN49?
No. The MDN range tops out at 10.2 cm. For longer viewing distances with multi-protocol input you must consider a custom build or a combination of GMR + MDN49 + NTDS84/86. Request advice from Daylight bv.
