STC-3028 24V Digital Temperature Humidity Controller

Dual Temperature & Humidity Control: Features independent dual relay outputs for simultaneous automated control of temperature systems (heating/cooling) and relative humidity (RH) equipment.

24V DC/AC Low-Voltage Operation: Operates safely on a 24V power supply, making it suitable for industrial control panels, automation cabinets, and low-voltage agricultural setups.

Dual High-Brightness Digital Display: Dual LED screen simultaneously displays real-time ambient temperature and humidity readings side-by-side for instant visual telemetry.

Included High-Precision Combo Probe: Bundled with an integrated temperature and humidity sensor probe for precise thermal and moisture sensing in air and microclimates.

Programmable Climate Parameters: Offers configurable hysteresis differentials, compressor/delay start protection, high/low limit alarms, and individual sensor calibration.

Housing Material: Flame-retardant ABS plastic panel-mount housing with side mounting tabs and protective screw terminal covers.

Technical Specifications:

Input Voltage: 24V DC/AC.

Temperature Range: $-20^\circ\text{C} – +80^\circ\text{C}$.

Humidity Range: $0\% – 100\%\text{ RH}$.

Relay Output Rating: 10A / 220VAC (per relay channel).

Housing Color: Grey / Black Casing with Red/Blue LED Displays.

Usage Advice: Verify 24V power connections before energizing; ensure load terminal screws are tightened securely to prevent high-resistance connection points.

Maintenance: Keep the combo sensor housing clean and free from dust buildup, heavy condensation, or oily residue to maintain measurement accuracy.

Essential 24V Climate Automation Hub: Position as an all-in-one environmental controller for 24V agricultural incubators, greenhouse climate loops, curing chambers, and industrial enclosure cooling/humidity management.

Highlight Combined Environmental Control: Emphasize how a single 24V unit manages both temperature (heater/fan) and humidity (humidifier/dehumidifier) simultaneously without requiring two separate controllers.

Recommended Cross-Sell Add-ons: Pair with STC-3028 12V Digital Temperature Humidity Controller, STC-3028 220AC Digital Temperature Humidity Controller, STC-3008 24V Thermostat Dual Temperature Controller, and ESD antistatic mat 50x40CM PCB Welding Mat.
