The PoE Digital Clock Description
The SP400-B-US is a professional-grade 2.3-inch PoE digital clock featuring a premium black stainless steel housing that offers exceptional durability and a sleek, modern aesthetic for offices, schools, and control rooms. Unlike standard time displays, this unit provides dual functionality: it can alternate between precise NTP-synchronized time and a US-standard calendar format (MM/DD/YY), or switch to a message board mode to display custom scrolling text up to 64 bytes. Powered entirely via Power over Ethernet (PoE), it eliminates the need for external power supplies and bulky wiring. The device connects directly to your local area network (LAN) to receive time updates from local or public NTP servers, ensuring maintenance-free operation with zero drift. Its high-contrast LED display ensures visibility in various lighting conditions, making it a perfect solution for facilities requiring accurate, synchronized timekeeping without the hassle of a master clock system.
The PoE Digital Clock Features
✔ Features a versatile display mode that supports US-style Calendar (MM/DD/YY) or custom scrolling text messages (limit of 64 bytes)
✔ Engineered with high network redundancy, supporting up to 5 different SNTP servers to guarantee continuous time synchronization.
✔ Offers flexible network configuration options with full support for both DHCP auto-allocation and Static IP addressing.
✔ User-selectable 12-hour or 24-hour time format with built-in logic for automatic Daylight Saving Time (DST) adjustments.
✔ Delivers ultra-precise timekeeping with an accuracy tolerance of ±20 milliseconds relative to the time server.
✔ Equipped with adjustable brightness settings, allowing users to optimize the LED intensity for dark or bright environments.
✔ Includes complimentary, user-friendly management software for easy batch configuration and monitoring.
✔ Expandable hardware design with optional support for Bell Relay control or external Temperature/Humidity sensor display.
