Conventional Temperature And Humidity Controllers LY-S2K

Product Advantages

Precision-Driven Humidity Control

With a humidity accuracy of ±5%RH and a control backlash range of 0~20%RH, the LY-S2K can stably maintain the target humidity range, avoiding sudden humidity changes that affect sensitive products or experiments. Its temperature monitoring accuracy of ±0.5℃ also provides auxiliary data support for comprehensive environmental regulation.

Redundant Monitoring & Safety Features

Equipped with Dual Humidity Sensors (Sensor 1 & Sensor 2), the controller achieves redundant monitoring: if one sensor malfunctions, the other immediately takes over to ensure uninterrupted control—critical for high-risk environments like pharmaceutical storage and electronic component workshops. Additionally, the built-in real-time humidity alarm system triggers alerts promptly when humidity deviates from set values, enabling users to respond quickly and reduce losses.

Energy Efficiency & Structural Durability

Boasting low power consumption (<2W), the LY-S2K is suitable for 24/7 continuous operation, significantly reducing long-term energy costs for enterprises. Its industrial-grade build can withstand harsh working conditions (operating temperature: -20℃~70℃; relative humidity ≤95%RH), and the compact size (48×48×78mm³) saves valuable installation space in control cabinets or equipment racks.

Technical Specifications

Core Technical Highlights

The LY-S2K’s technical parameters are optimized for humidity control, with key highlights including: compatibility with standard industrial power supplies (AC 220±10% 50Hz), a wide humidity control range (0~99%RH), and a dual working voltage load capacity of 3A—supporting most common humidity-adjustment devices. Its 1000V AC pressure resistance (50Hz, 1 minute) ensures electrical safety in complex industrial circuits.

Applications

Food Storage & Preservation

In grain depots, fruit warehouses, and cold storage facilities, the LY-S2K maintains optimal humidity (e.g., 6070%RH for grains, 8590%RH for fruits) to prevent mold growth, moisture loss, and spoilage, effectively extending the food shelf life and reducing waste.

Electronics Manufacturing Cleanrooms

In semiconductor, circuit board, and electronic component production workshops, the controller regulates humidity to 45~65%RH, avoiding static electricity generated by low humidity that can damage sensitive electronic components, thus ensuring product quality stability.

Scientific Research Laboratories

For biological culture, material aging tests, and chemical experiments that require precise humidity, the LY-S2K provides a stable environment, ensuring the repeatability and reliability of experimental data, making it an essential auxiliary device for research institutions.

Commercial HVAC Systems

Integrated with central air conditioning and ventilation systems in shopping malls, office buildings, and hotels, the controller adjusts indoor humidity to a comfortable range (40~60%RH), improving indoor air quality and enhancing human comfort.

Selection Guide

Humidity Requirement Matching

Choose the LY-S2K if your application requires dual-zone humidity monitoring (e.g., separate storage zones in a warehouse) or high-precision humidity regulation (±5%RH). It is not recommended for scenarios where temperature control is the primary focus (opt for the LY-W2K instead).

Input Module & Accessory Selection

Pair the controller with the ALE-S2K input module (specifically designed for 2 humidity inputs) to enhance signal transmission stability and data accuracy. For wiring convenience, select compatible sensor extension cables (≤5m) to avoid signal attenuation.

Optional Feature Customization

For critical applications (e.g., pharmaceutical storage, precision electronics production), add the disconnection alarm function to receive timely alerts if sensors or connecting wires fail, preventing unmonitored humidity deviations.

Operation Guide

Pre-Operation Setup

Power Connection: Connect AC 220V power to terminals 6-10 (AC input) and terminal N (neutral wire); ensure correct wiring to avoid short circuits or equipment damage.

Sensor Installation: Mount Sensor 1 and Sensor 2 in representative areas (avoid direct sunlight or air vents) and secure wiring to prevent loose connections.

Daily Control & Mode Switching

Threshold Setting: Press the "Auto/Manual" button to enter setup mode; use the adjustment keys to set the upper and lower humidity limits (e.g., 40%RH lower limit, 60%RH upper limit) and confirm.

Mode Selection: Use "Auto Mode" for daily operation; switch to "Manual Mode" only for emergency adjustments (e.g., sudden humidity spikes), and revert to auto mode once the issue is resolved.

Routine Calibration & Maintenance

Sensor Calibration: Calibrate both sensors every 6~12 months using a standard humidity calibrator to ensure measurement accuracy.

Alarm Testing: Monthly test the alarm function by adjusting humidity beyond preset thresholds to confirm the alert works normally.

Cleaning & Inspection: Regularly wipe the sensor surface to remove dust; check wiring terminals quarterly for looseness or corrosion.
