Honda Marysville has requested DC-Digital for a method of regulating how long it takes for custom paint jobs to be done in auto shop. This custom DC-25T-DN-BCD-NEMA countdown timer is designed to bring precision and repeatability to paint booth operations in automotive shops, giving users full control over how long parts remain in the painting process. Built around a simple yet highly effective interface, this unit allows operators to quickly set and manage countdown cycles using integrated BCD rotary switches and external plug-and-play input devices. The result is a streamlined workflow where timing consistency directly supports quality control and efficiency on the shop floor.

At the core of this system is the ability to define a countdown duration in seconds using the internal BCD rotary switches. These switches are located inside the enclosure and allow the user to precisely select the desired countdown value before operation begins. Once set, the timer can be triggered using a customer-supplied input device connected through the terminal block, making it easy to integrate into existing paint booth setups. Whether starting or stopping the cycle, the control process is straightforward and responsive, ensuring operators can manage timing without unnecessary complexity.

During operation, the display clearly shows the countdown in seconds, including tenths and hundredths of a second for added precision. For example, when set to 99 seconds, the unit begins counting down immediately upon activation. Pressing the connected start/stop input halts the countdown at its current value, and pressing it again resumes from that exact point rather than resetting. This functionality is particularly useful in real-world paint applications where interruptions may occur but timing accuracy must still be preserved.

When the countdown reaches zero, the unit provides a clear visual indication by flashing the LED display. This alerts the user that the cycle is complete and signals that the process—such as paint curing or coating duration—has finished. From there, the timer is ready to be restarted using the preset value defined by the BCD rotary switches.

Accessing and configuring the unit is designed to be simple and secure. By powering down the system and removing the front cover with a standard Phillips head screwdriver, users can access both the BCD rotary switches and the terminal block. The rotary switches can then be adjusted with a flathead screwdriver to set a new countdown value. The terminal block, located at the top of the enclosure, is clearly labeled and allows for easy wiring of input devices. For example, a typical configuration might involve connecting the control input to terminal one and the common wire to terminal four, enabling start/stop functionality through an external button or switch.

Key functional highlights of the DC-25T-DN-BCD-NEMA include:

• Adjustable countdown timing using internal BCD rotary switches
• Precise time display in seconds, tenths, and hundredths (up to 99 seconds)
• Start/stop control via customer-supplied plug-and-play input devices
• Resume functionality that continues from the paused time without resetting
• Visual LED flash alert when countdown reaches zero

From a software and operational standpoint, this unit is purpose-built for environments where consistent timing is critical. By limiting the countdown strictly to seconds and sub-second increments, it eliminates unnecessary complexity while delivering the level of precision required for controlled paint applications.

Additional system characteristics that support its functionality include:

• Clear numeric display for real-time countdown visibility
• Internal configuration interface for quick time adjustments
• Structured input control through a labeled terminal block system
• Reliable countdown behavior tailored for repetitive industrial processes

Overall, the DC-25T-DN-BCD-NEMA provides a focused, efficient timing solution for paint booth operations. Its combination of precise countdown control, simple user interaction, and flexible input integration makes it a dependable tool for ensuring consistent coating durations and improving overall process control in automotive finishing environments.
