Digital Time, Date and Frequency Displays

An NTP digital clock display is an LED wall or panel clock that sets itself from a Network Time Protocol server on your Ethernet network. Instead of keeping its own time, it follows the server, so every display in the building shows the same second as your computers, PLCs and recording systems.

NTP displays receive time over a standard Ethernet LAN and suit buildings that already have network cabling and a time server. IRIG-B displays take a dedicated timecode or differential pulse signal from a master clock, which suits power plants and substations that keep timing separate from the IT network.

The T-SL-300-100-6D slave clock supports up to 300 displays on a single master clock across a radius of up to 1 km, connected on a multi-drop bus. Larger or more spread-out sites use distribution units and signal boosters.

Choose by viewing distance and lighting. 14 mm suits panel fronts and racks read from arm's length, 100 mm covers offices, control rooms and corridors, and 150 mm serves large halls and warehouses. Character sizes of 200 mm and 300 mm are also available on request, and our engineers can recommend a size from your floor plan.

Yes. The 100 mm and 150 mm time displays use weather-proof construction rated IP55 as standard, with IP66 available for outdoor applications. They are specified for ambient temperatures from -10 °C to +85 °C and 0 to 90% relative humidity, non-condensing.

Nothing changes for the others. Slave displays connect in multi-drop mode, so the loss of any single unit does not interrupt the time shown on the remaining displays in the network.

Yes. The alphanumeric display reads values through Ethernet, OPC or 4-20 mA inputs, so it can show parameters such as frequency, MW output, air quality or temperature next to time and date. It restores the displayed data automatically after a power interruption.

The 100 mm and 150 mm time displays use an SMPS with universal 90 to 260 V AC/DC input. The alphanumeric display runs on 230 V AC. Check the datasheet of each model for its exact rating.
