It uses an NTC thermistor probe (included) for measurement across a wide range of −50 to 110°C.\n\nThe relay operates as normally open and closes when the measured temperature rises above the set point. It re-opens once the temperature falls 2°C below the set point, providing built-in hysteresis to prevent rapid relay cycling.\n\nKey Features\n\n\n3-Digit LED Display – Shows current temperature and set-point during configuration\n\n10A Relay Output – Normally open, switches at the set temperature with 2°C hysteresis\n\nWide Measurement Range – −50 to 110°C with ±0.1°C accuracy\n\nWaterproof NTC Probe – 10K (0.5%) sensor included for reliable temperature sensing\n\nPanel-Mount Design – Compact module fits a 46 × 26.5 mm panel cutout\n\n\nSpecifications\n\n\nInput Power – 12V DC\n\nTemperature Range – −50 to 110°C\n\nAccuracy – ±0.1°C\n\nControl Resolution – 0.1°C\n\nRefresh Rate – 0.5 s\n\nHigh-Temperature Protection – 0 to 110°C\n\nSensor – NTC 10K (0.5%), waterproof\n\nStatic Current – ≤35 mA\n\nRelay Active Current – ≤65 mA\n\nOperating Environment – −10 to 60°C, 20–85% humidity\n\nModule Size – 48.5 × 40.1 × 15.8 mm\n\nPanel Cutout – 46 × 26.5 mm\n\nWeight – 22.3 g\n\n\nIdeal For\n\nHomebrew and fermentation temperature control\nIncubator and terrarium heating systems\n3D printer heated bed or enclosure regulation\nAquarium and hydroponic temperature monitoring\n\n\nPackage Contents\n\n1× 12V Temperature Controller Module\n1× Waterproof NTC Temperature Probe\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5828,"title":"Default Title","sku":"LB-LR0214-16","price":8.05,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":112,"option1":"Default Title"}]}
