Sierra Products, a manufacturer’s representative for Process Technology, required a dependable countdown timer for an acid bath system supplied to Honeywell. While Process Technology designed and provided the heating and cooling equipment used in the wet processing system, a dedicated timer was needed to accurately monitor the immersion cycle.

The Application

Accurate timing is essential in chemical processing environments where parts must remain immersed for a precise duration. Even a small timing error can affect product quality, process consistency, and operator safety. DC-Digital provided a custom countdown timer solution for an acid bath application that helps automate timing while protecting the equipment from harsh industrial conditions.

The timer needed to provide a simple operator interface while also withstanding exposure to corrosive chemicals commonly found in industrial acid bath environments.

The Solution: DC-10T-DN-NEMA Countdown Timer

DC-Digital supplied the DC-10T-DN-NEMA Countdown Timer, a compact industrial timer designed to provide accurate countdown operation and reliable equipment control.

The timer is programmed with the required process duration before each cycle begins. Once the operator presses the sealed start button, the display counts down toward zero, providing a clear visual indication of the remaining processing time. When the countdown reaches zero, the operator is immediately notified that the acid bath cycle has been completed and the part can be safely removed.

To further automate the process, the timer includes an integrated relay output module. The relay can activate or deactivate external equipment when the countdown expires, allowing the timer to control pumps, alarms, indicator lights, or other process equipment without additional operator intervention.

Designed for Corrosive Environments

Industrial chemical processing environments demand equipment that can withstand moisture, chemicals, and continuous operation. For this application, the timer was configured with several protective features to maximize reliability.

Key features include:

• Compact enclosure measuring approximately 4 inches high
• Bright 1-inch LED countdown display
• Durable polycarbonate NEMA enclosure for corrosion resistance
• Sealed push-button controls to prevent chemical intrusion
• Transparent smoked viewing lens for excellent display visibility while protecting internal electronics
• Relay output for automatic equipment control at the end of the countdown cycle

These design features allow the timer to operate reliably even when installed near corrosive acid bath equipment.

Benefits of Automated Countdown Timing

Using a dedicated industrial countdown timer improves both process accuracy and operational efficiency. Operators always know exactly how much time remains during each cycle, eliminating guesswork and reducing the risk of under-processing or over-processing valuable components.

The integrated relay output also enables process automation, helping reduce manual intervention while improving consistency between production cycles.

Industrial Countdown Timers Built for Demanding Applications

DC-Digital manufactures countdown timers for a wide variety of industrial processes, including chemical processing, manufacturing, plating operations, cleanrooms, production lines, laboratories, and automated equipment. Each timer can be customized with enclosure options, relay outputs, control methods, display sizes, and environmental protection features to meet the requirements of virtually any application.

Whether timing an acid bath, controlling a manufacturing process, or automating industrial equipment, DC-Digital countdown timers deliver dependable performance, precise timing, and long-term reliability in demanding industrial environments.
