The SUL181d: A Paragon of Versatility and Resilience in 24-Hour Timing

In the intricate ecosystem of industrial automation, building management, and energy control, the reliability of a timing device is non-negotiable. The SUL181d 24-Hour Programmable Timer emerges as a sophisticated and robust solution, engineered to deliver precise, uninterrupted control in a wide array of applications. Building upon a legacy of dependable electromechanical timing, this model introduces critical enhancements in power reserve and operational flexibility, establishing itself as an indispensable asset for system designers and facility managers who cannot afford downtime.

Universal Compatibility and Robust Construction

The SUL181d is designed from the ground up for global deployment and ease of integration. Its most striking feature is its universal operating voltage of AC 110V/220V/240V at 50-60Hz. This remarkable flexibility eliminates the need for specific regional models or external voltage converters, significantly simplifying inventory management and installation for multinational operations. The device consumes a mere 2.5VA, underscoring its energy-efficient design. Installation is streamlined via DIN rail mounting, the industry standard for electrical enclosures, allowing for quick, secure, and organized placement alongside contactors, circuit breakers, and other control gear. With compact dimensions of 90x54x65mm and a weight of only 152g, it optimizes panel space without compromising on performance.

Unwavering Precision in Timekeeping

At the core of the SUL181d's functionality is its exceptional timekeeping accuracy, rated at ≤2 seconds per day at 25°C. This precision, governed by a high-quality quartz-controlled movement, ensures that all switching events occur exactly as scheduled. Whether orchestrating the start-up of machinery at the beginning of a shift, controlling security lighting to deter intruders, or managing ventilation systems for optimal air quality, users can have absolute confidence in the timer's chronological reliability. This level of accuracy is crucial for processes where timing is intrinsically linked to safety, efficiency, and consistency.

Powerful Switching for Diverse Loads

A timer's true test lies in its ability to handle real-world electrical loads, and the SUL181d is equipped to manage a broad spectrum with ease. Its contact capacity is impressively rated for various load types. For resistive loads, such as heating elements or incandescent lighting, it can handle 16A at 250V AC. It is specifically rated for a lamp load of 1000W, making it ideal for commercial and industrial lighting control. Furthermore, it competently manages more challenging inductive loads (e.g., contactor coils, solenoid valves, small motors) at 3A/250V AC (cosΦ=0.6). The low contact resistance (≤50mΩ) and high insulation resistance (≥100MΩ) ensure minimal power loss and enhanced operational safety, protecting both the timer and the connected equipment.

Intuitive Programming and Operational Flexibility

The SUL181d offers extensive programming capabilities tailored for complex daily schedules. It operates on a 24-hour cycle with a minimum setting unit of 15 minutes. This granularity allows for 96 potential on/off events within a single day. Such fine control enables highly optimized routines, such as cycling pumps to prevent wear, managing display lighting in a retail environment, or controlling HVAC in unoccupied spaces to achieve significant energy savings. The "15 minutes/time, 96 time" setup structure provides a logical and intuitive framework for creating everything from simple daily schedules to highly complex, multi-event sequences, all without the need for advanced software or networking.

The Defining Feature: Unprecedented Power Reserve

A standout feature that distinguishes the SUL181d from conventional timers is its formidable built-in power reserve. The integrated storage battery allows the timer to maintain its program and clock for an exceptional 200 hours (over 8 days) after a full 24-hour charge at 220V (100 hours at 110V). This capability is a game-changer for applications where power outages are a concern. In the event of a mains failure, critical timing schedules are not lost. Once power is restored, the SUL181d continues its programmed operation seamlessly, eliminating the need for manual resets and preventing disruptive deviations in automated processes. This ensures continuity in security protocols, agricultural operations, and industrial cycles, providing unparalleled peace of mind.

Built for Demanding Environments

Engineered for resilience, the SUL181d is built to perform reliably in a wide range of conditions. Its specified operating temperature range of -10°C to +55°C guarantees stable performance in environments from chilly, unheated warehouses to hot industrial control panels. This ruggedness ensures that the timer will function as intended, regardless of seasonal temperature fluctuations.

Conclusion: The Intelligent Choice for Critical Automation

The SUL181d 24-Hour Programmable Timer is more than a simple switching device; it is a comprehensive control solution that masterfully blends precision, power, and intelligence. Its universal voltage acceptance, robust 16A switching capacity, and highly flexible 96-segment programming make it a versatile choice for countless applications. However, it is the revolutionary 200-hour power reserve that truly sets it apart, offering a level of operational resilience that is critical in today's world. For system integrators, industrial engineers, and facility managers seeking a reliable, versatile, and fail-safe timing solution, the SUL181d represents the pinnacle of electromechanical timer technology, ensuring that time-critical operations proceed without interruption, day after day.
