Product Overview
The ATC-HHMMSS-L LED wall clock is a 6-digit digital LED clock designed to display time in hour, minute, and second format clearly and accurately.
This product is suitable for offices, factories, warehouses, cold storage areas, production zones, control rooms, technical rooms, and other environments where continuous and easy-to-read time display is required.
With a 7-segment LED display, large digit size, and default red LED color, the clock allows operators, workers, staff, and visitors to view the time easily from a distance. Its wall-mounted design, black aluminum alloy frame, and protective mica front panel make it suitable for both industrial and commercial environments.
Why Choose the ATC-HHMMSS-L LED Wall Clock?
In factories, warehouses, and operation areas, clear time display is not only used for basic time checking. It also supports shift management, production process tracking, work schedule control, break time management, and coordination between different departments.
The ATC-HHMMSS-L LED wall clock is designed with 6 large LED digits to display hour, minute, and second clearly. This helps users check the time faster than traditional analog clocks, especially in large areas where quick time recognition is important.
For projects that require unified time display across multiple areas, this product can also work together with an NTP clock system for time synchronization. This makes it suitable for facilities that need more consistent time management between production rooms, offices, operation areas, and technical zones.
The clock uses low-power LED technology and is suitable for continuous daily operation. It is easy to install, easy to adjust, and suitable for businesses that need a durable and stable LED wall clock for professional environments

Main Applications
The ATC-HHMMSS-L LED wall clock can be used in many indoor locations, including manufacturing factories, warehouses, logistics centers, cold storage rooms, production workshops, offices, control rooms, technical rooms, schools, hospitals, and service areas.
In industrial environments, the clock helps workers and supervisors follow production time, shift schedules, and operation timing more clearly. In warehouse and logistics environments, it supports better time awareness for receiving, dispatching, loading, and daily operation activities.
In office, control room, or technical environments, the clock provides a clear central time display and can support facilities that also use a server room monitoring and alarm system for better infrastructure operation.
Because the product displays hour, minute, and second, it is especially useful in areas where time tracking needs to be more detailed than a standard hour-minute clock.
Key Features
Clear 6-Digit LED Display
The ATC-HHMMSS-L uses a 6-digit LED display to show hour, minute, and second clearly. The large LED digits allow users to read the time from a distance, making it suitable for wide areas such as factories, warehouses, and control rooms.
Large Wall-Mounted Design
With an overall size of 180mm x 600mm x 50mm, the clock has a long and slim design that can be mounted easily on the wall without taking up much space. This design makes it suitable for installation above entrances, on production area walls, in offices, or in central monitoring areas.
High-Visibility LED Color
The product uses red LED as the default display color, helping improve visibility in indoor environments. Depending on project requirements, other LED color options such as amber, blue, or green may also be available.
Energy-Saving Operation
The clock uses low-power LED technology, helping reduce operating costs when continuous time display is required. This is important for factories, warehouses, and other areas where the device needs to operate stably for long periods.
Durable Frame and Clean Appearance
The black aluminum alloy frame provides a strong, modern, and professional appearance. The mica front panel protects the display area and keeps the clock clean, clear, and suitable for industrial or commercial working environments.
Easy Time Adjustment
Users can adjust the time using the control buttons located on the right side of the display. This simple design makes setup and operation easy without complicated procedures.
Optional Modbus RTU RS485 Communication
For projects that require integration with control or monitoring systems, the product can support optional Modbus RTU RS485 communication. This function is suitable for automation systems, factories, or applications that need to connect the time display device with a central management system.
