The DC-300-W-System-IN is a powerful and purpose-built wireless master-secondary time-of-day clock system designed specifically for high-efficiency logistics environments like Amazon’s Distribution Centers. This system consists of a pair of DC-300-W units configured in a Master-Secondary relationship, enabling seamless and accurate time synchronization across large operational areas.

At its core, the DC-300-W-System-IN is all about reliability, precision, and flexibility. The Master unit transmits the time-of-day data wirelessly to the Secondary unit, which is equipped with store-and-forward functionality. This means the Secondary unit not only mirrors the time data but can also pass that data along to additional secondary clocks, allowing for virtually unlimited scalability within the wireless network.

Key Features and Specifications:

• Wireless Data Synchronization:
  The Master clock communicates over a 2.4 GHz radio frequency using a built-in 64 mW transmitter, enabling a strong signal that can cover up to 1,500 feet. This ensures wide-area coverage without the need for wiring.
• Store-and-Forward Capability:
  The Secondary unit receives time data from the Master and can relay it forward to multiple other units, providing network resilience and easy expansion for future needs.
• Large, High-Visibility Display:
  Each unit features 30-inch high red LED digits, ensuring visibility from long distances—ideal for large, open warehouse environments.
• Durable Enclosure and Flexible Mounting:
  The clocks are housed in an all-extruded aluminum enclosure, making them rugged enough for industrial spaces. They come with two adjustable mounting rails for either wall mounting or aerial suspension from ceilings or rafters, allowing for versatile installation.
• Custom Power Setup:
  While these clocks are typically 120V operated and shipped with power cords, the customer (Amazon) requested a junction box configuration, which we readily accommodated. Customization is always available to fit specific facility requirements.
• Handheld Wireless Controller:
  The system includes a wireless handheld controller that simplifies clock setup and synchronization. With just a few button presses, you can:
  • Set hours and minutes independently
  • Automatically reset seconds during setup
  • Configure for 24-hour format
  This user-friendly setup ensures that even non-technical staff can easily manage time synchronization.

Real-World Application

In this deployment, the DC-300-W-System-IN will be used to manage truck dispatching and load coordination within an Amazon Distribution Center. Time accuracy and high visibility are critical for this application, allowing staff to coordinate loading operations, track deadlines, and maintain a smooth and consistent shipping schedule.

Whether you’re managing a complex logistics operation or looking to upgrade your facility with modern time-keeping systems, the DC-300-W-System-IN offers a scalable, easy-to-use, and reliable solution that adapts to your operational needs.

Stay tuned for more innovations like this one—custom-engineered for performance, durability, and precision.
