Products / PoE / RJ45 Slave Clocks / ORNATE NT-156
Single-cable digital LED slave clock — power and NTP time delivered over the same RJ45 drop. ORNATE 7000 Series.
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.
Available in red, white, blue and green 6-digit 7-segment LED — single-sided or double-sided, 100mm display size.
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.
±1 microsecond of UTC/GMT/IST via NTP/SNTP, synchronizing every second. Display accuracy rated at ±40 milliseconds under normal operation.
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.
Any time zone supported with external time-zone selection, 12/24-hour display, and automatic daylight saving time adjustment.
Three-stage brightness switch, minimum to maximum, with software-adjustable digit light intensity for indoor and outdoor visibility — readable from 25 metres.
High-strength plastic (black) or metal cabinet, protected against dust and water. Operating range 0–60°C at up to 90% relative humidity.
Configure over TCP/IP, DHCP or ICMP via a simple browser or software interface — no proprietary tools required. IRIG port included.
Wall-mounted or panel-mounted, aluminium or MS sheet metal body with powder coating. Single-sided or double-sided display configurations available.
