Master-Clocks

Master Clocks

Master clocks serve as a central reference within a synchronized clock installation.

They can be used as part of systems containing multiple synchronized clock displays.

Slave-Clocks

Slave Clocks

Slave clocks receive time information from a master clock or centralized time source to maintain synchronized time.

They are designed for installations where multiple clock displays need to follow a common reference time.

Wired-Synchronized-Clocks

Wired Synchronized Clocks

Wired synchronized clocks use a physical communication connection to distribute time information between the synchronization source and connected clocks.

They are suitable for installations where a dedicated wired clock network is preferred.

GNSS-Synchronized-Clocks

GNSS Synchronized Clocks

GNSS synchronized clocks use signals from compatible Global Navigation Satellite System sources to obtain a reference time.

They provide a satellite-based synchronization option for suitable clock installations.

GPS-Synchronized-Clocks

GPS Synchronized Clocks

GPS synchronized clocks use GPS signals as an external time reference.

They can be used where satellite-based time synchronization is required for a clock installation.

Time-Zone-Synchronized-Clocks

Time Zone Synchronized Clocks

Time zone synchronized clocks are designed to display synchronized time for different time zones within the same facility or clock installation.

They are suitable for locations where teams, operations or visitors need to reference time in multiple regions.

Define Your Clock Requirements

Use the following requirements to narrow your product selection and prepare your enquiry. Include the details you already know, and check the selected product’s specifications before confirming a configuration.

Display Requirements

Need-a-Large-Digital-Display

Specify your preferred digital or analog display, approximate viewing distance and required display size. For digital clocks, note whether you need hours and minutes, seconds, date information or multiple time zones. Indicate whether the display will be viewed from one direction or from opposite sides.

Installation Requirements

Slave-Clocks

Describe the proposed mounting position, available space and viewing angle. Include the mounting height and whether the clock will be installed on a wall, suspended from a ceiling or fitted into another structure. Note any moisture, dust, weather exposure or cleaning requirements that need to be considered.

Power Requirements

Need-Power-and-Network-Through-One-Cable

Identify the power source available at each clock location, such as an electrical outlet, an existing low-voltage supply or PoE equipment. Include the supply voltage or PoE specifications where known. State the power requirements separately from the preferred network or communication connection.

Connection Requirements

Need-Ethernet-Connectivity

Describe the available Ethernet or Wi-Fi network, dedicated wireless clock equipment or existing clock wiring. Where known, provide the time synchronization protocol and communication interface. For existing cables, include connection details rather than relying on the cable or connector appearance alone.

Quantity & Location Requirements

Need-a-Central-Reference-Clock

Provide the estimated number of clocks and how they will be distributed across buildings, floors or departments. Identify locations requiring different display sizes, mounting arrangements or connections. Include any planned additions so the initial requirements and future expansion can be reviewed together.

Compatibility Requirements

Time-Zone-Synchronized-Clocks

For replacement clocks or extensions to an existing installation, provide the manufacturer and model of the current master clock or time server and receiving clocks. Share available manuals, equipment labels and connection details. Identify any existing equipment that must remain in service.

Need Help Selecting a Product?

If you already know the required clock type, display size, quantity or connection method, you can proceed directly to the relevant product category.

If your requirements are not yet defined, provide the basic project information and HC Electronics can help identify suitable product configurations.

Need-Help-Selecting-a-Product

Synchronized Clock Selection Questions

Yes. Display format, network connection and power supply describe different characteristics, so a clock may belong to more than one category. Review the individual product page to confirm which features are available together.

Compatibility needs to be checked before selecting additional clocks. Share the existing master clock or time server details, communication interface, power arrangement and current clock models so the connection requirements can be reviewed.

Send the requirements you already know using the enquiry form below. You do not need a complete specification to begin. Include any available site plans, equipment photos or technical documents, and indicate which details still need to be confirmed.
