SUL181h: The Robust and Reliable 24-Hour Programmable Timer for Demanding Industrial and Commercial Applications

The SUL181h Programmable Timer stands as a quintessential solution for automating electrical circuits with precision and unwavering reliability. Engineered to meet the rigorous demands of industrial control panels, commercial building management, and energy control systems, this timer combines a versatile power supply, substantial switching capacity, and intelligent battery backup in a compact, DIN-rail mounted package. It is designed for professionals who require a set-and-forget device that delivers consistent performance day after day.

Versatile Global Operation and Efficient Power Design

A key feature of the SUL181h is its broad compatibility with common global power standards. The unit operates on AC voltages of 110V, 220V, and 240V at 50-60Hz, eliminating the need for region-specific models and simplifying procurement for international projects and supply chains. With a low power consumption of just 2.5VA, it is an energy-efficient component that minimizes its own operational footprint within a larger electrical system. This versatile power design ensures easy integration into existing infrastructure without requiring complex adjustments or external transformers.

Robust Switching Capability for Diverse Loads

The heart of any timer is its ability to switch loads reliably, and the SUL181h excels in this domain. Its contact capacity is rated for a robust 16A at 250VAC for resistive loads (cosΦ=1), making it suitable for controlling heaters, industrial lighting, and other high-power non-inductive equipment. Recognizing the challenges of inductive loads, it also boasts a solid 3A at 250VAC rating (cosΦ=0.6), allowing it to confidently control small motors, contactor coils, and solenoids without risk of premature contact welding or failure. For lighting-specific applications, a dedicated 1000W lamp load rating ensures it can handle the high inrush currents of incandescent and halogen lighting systems. The high insulation resistance (≥100MΩ) and low contact resistance (≤50MΩ) further guarantee safe operation and long-term electrical integrity.

Precision Timing with Uninterrupted Memory

At its core, the SUL181h is a precision timing instrument. It offers a full 24-hour programming cycle with a minimum setting unit of 30 minutes. This allows for the creation of highly detailed daily schedules, with the capacity for up to 48 separate on/off switching events within a single day. The device's exceptional accuracy of ≤2 seconds per day at 25°C ensures that these schedules remain perfectly synchronized over the long term, a critical feature for time-sensitive processes and energy-saving protocols. Furthermore, the integrated storage battery provides a remarkable 150 hours of reserve time after a 24-hour charge, safeguarding all programmed settings and maintaining clock accuracy through extended power outages. This ensures the system resumes its scheduled operations seamlessly once power is restored, without requiring manual reprogramming.

Engineered for Durability and Seamless Integration

Built to thrive in challenging environments, the SUL181h operates reliably within a temperature range of -10℃ to +55℃. Its compact dimensions of 90x54x65mm and a weight of 152g make it a space-saving solution for crowded control panels. The industry-standard DIN rail mounting (EN/IEC 60715) facilitates quick and secure installation alongside circuit breakers, contactors, and other automation components, significantly reducing wiring and assembly time.

In summary, the SUL181h Programmable Timer is a masterclass in balanced design, offering power, precision, and resilience. It is an ideal, cost-effective choice for a wide array of applications, including industrial machinery sequencing, commercial HVAC control, smart lighting systems in offices and warehouses, and automated agricultural or irrigation systems. By choosing the SUL181h, engineers and system integrators select a component that guarantees operational consistency and enhances the intelligence and efficiency of any electrical installation.
