Products  /  PoE / RJ45 Slave Clocks  /  ORNATE NT-156

Overview

One Cable. Always in Sync.

The ORNATE NT-156 is a PoE/RJ45-powered NTP slave clock that draws both power and precise network time over a single Ethernet cable. It synchronizes every second against your NTP/SNTP time server to within ±1 microsecond of UTC/GMT/IST, and keeps running accurately on a battery-backed real-time clock even if the network connection is temporarily lost — resyncing automatically the moment it's restored.

ORNATE NT-156 NTP PoE Clock — red, green and blue 6-digit LED display models

Available in red, white, blue and green 6-digit 7-segment LED — single-sided or double-sided, 100mm display size.

Key Features

Built for Set-and-Forget Accuracy

🔌

PoE or DC Power

Runs on Power over Ethernet or a standard DC adaptor — 12V/1A for red display, 18V/1A for red/white/blue/green. One cable for power and data where PoE is used.

🎯

Microsecond-Class Accuracy

±1 microsecond of UTC/GMT/IST via NTP/SNTP, synchronizing every second. Display accuracy rated at ±40 milliseconds under normal operation.

🔋

Battery-Backed RTC Holdover

An internal battery-backed real-time clock keeps UTC time live if synchronization fails — minimum 4 hours backup — and auto-resyncs the instant the connection returns.

🌍

IST / GMT / UTC Selectable

Any time zone supported with external time-zone selection, 12/24-hour display, and automatic daylight saving time adjustment.

💡

Adjustable Brightness

Three-stage brightness switch, minimum to maximum, with software-adjustable digit light intensity for indoor and outdoor visibility — readable from 25 metres.

🛡️

IP66/67 Rated Housing

High-strength plastic (black) or metal cabinet, protected against dust and water. Operating range 0–60°C at up to 90% relative humidity.

🖥️

Browser-Based Configuration

Configure over TCP/IP, DHCP or ICMP via a simple browser or software interface — no proprietary tools required. IRIG port included.

📐

Flexible Mounting

Wall-mounted or panel-mounted, aluminium or MS sheet metal body with powder coating. Single-sided or double-sided display configurations available.
