NT24k®-DR16 Modular Industrial Switch
N-Tron® Networking Series
Managed Gigabit Industrial Ethernet Switch
The N-Tron® series NT24k®-DR16 is a modular managed switch
designed for factory automation, utilities, security surveillance,
SCADA and other industrial applications.
The Red Lion N-Tron series NT24k-DR16 managed industrial Ethernet switch features connectivity for
up to 16 Gigabit ports and offers a wide range of connectivity options—including 100Base, Gigabit,
fiber optic and copper options—in a rugged DIN-rail mountable enclosure. Designed to handle the
most demanding environments, the NT24k-DR16 delivers wire-speed throughput and includes
expanded shock and vibration tolerances, extreme operating temperature range and two slots to
accommodate mix-and-match port modules. N-Ring™ technology restores network communication
within ~30ms of fault detection. Robust remote monitoring capabilities make management easy.
