XH-W1219 DC 12V Dual Display Digital Thermostat

Dual Digital LED Telemetry Displays: Features two distinct LED displays showing real-time measured temperature and target setpoint temperature simultaneously for effortless monitoring.

12V DC Low-Voltage Operation: Powered directly by a 12V DC input, making it ideal for automotive projects, battery systems, off-grid solar, and low-voltage enclosures.

Dual Heating & Cooling Mode Support: Configurable operational modes allow seamless switching between heating (e.g., thermal pads) and cooling (e.g., Peltier elements, 12V fans) systems.

Onboard 10A Switching Relay: Heavy-duty relay output directly commands external loads up to 10A / 12V DC or 10A / 220V AC.

Bundled Waterproof NTC Probe: Equipped with a waterproof thermistor sensor probe for accurate thermal detection in air, liquids, or moist environments.

Board Material: High-grade FR-4 glass-epoxy PCB with dual LED modules, tactile setting buttons, and heavy-duty terminal blocks.

Technical Specifications:

Operating Voltage: 12V DC.

Temperature Control Range: -50°C – +110°C.

Control Precision: 0.1°C.

Relay Output Rating: 10A / 12V DC or 10A / 250V AC.

Board Color: Green PCB with Black Switching Relay.

Usage Advice: Verify 12V DC power input polarity before powering on; secure load leads into terminal blocks firmly to prevent voltage drop or resistive heating.

Maintenance: Keep the circuit board free from dust, moisture, and metallic fragments to maintain accurate readings and prevent short circuits.

Essential Dual-Display Thermal Engine: Position as a user-friendly open-board thermostat for DIY incubators, aquarium heating/cooling, fermentation chambers, and electronic cooling systems.

Highlight Dual-Display Convenience: Emphasize how viewing current and target setpoint temperatures side-by-side eliminates the need to navigate setup menus during routine checks.

Recommended Cross-Sell Add-ons: Pair with W1209 DC 12V Digital Thermostat, W1209 Acrylic shell protective case, XH-W1401 Thermostat Temp Controller, and ESD antistatic mat 50x40CM PCB Welding Mat.
