anicorn W1209 12V DC Digital Thermostat 3-pack -50-110°C 10A Relay

SKU CH-Q3H6-ARYYT

Three 12 V digital thermostats with 0.1 °C precision, -50 to 110 °C range and 10 A relays for heating or cooling control

  • 1 °C precision lets you fine-tune processes
  • 50 to 110 °C range covers freezing to boiling water
  • 10 A relay switches heaters or coolers directly
  • 12 V DC supply suits vehicle and bench power
  • Waterproof NTC probe measures air or liquid temperature

Three-pack thermostat modules

Each pack supplies three W1209 boards ready for independent temperature tasks. The modules run from a 12 V DC source and include a waterproof NTC probe for liquid or air sensing. Hobbyists, aquarium keepers and small-appliance builders can deploy them in parallel without sharing a single controller.

Range and precision limits

Measurement spans -50 °C to 110 °C with a control precision of 0.1 °C. The 10 A relay switches heating or cooling loads directly, but the single-channel output cannot drive multiple separate circuits. Accuracy relies on the onboard STM8S microprocessor and the calibrated probe.

Build integration notes

Each board fits inside its supplied plastic case and exposes screw terminals for power, sensor and load wiring. The 3-digit LED display remains readable in bright light, and the keypad sets modes without external tools. Users must provide a 12 V supply, mounting hardware and any enclosures beyond the included cases.

Questions about this item

Will the 12 V DC supply on my existing control panel run the W1209 board without extra conversion?

Yes, the module operates directly from 12 V DC so it can share the same supply as other 12 V equipment.

How can I verify the 0.1 °C control precision once the NTC probe is installed?

Compare the LED readout with a calibrated reference thermometer; the display should track within one-tenth of a degree.

Does the 3-pack include three waterproof NTC probes and three enclosures, or must I order them separately?

Each of the three boards comes with its own waterproof probe and case, so no additional parts are needed for basic operation.
