3PCS DC 12V XH-W1209 Thermostat Temperature Heat Sensor Switch -50℃~110℃ Digital Temperature Controller Board LED Display with Waterproof NTC Sensor Probe + 3PCS Case
【W1209 Parameter】Temperature range: -50°C~110°C; Control precision: 0.1 °C.Input power (DC): 12V; Measuring inputs: NTC (10K 0.5%) ; Waterproof sensor: 0.5M; Output: 1 channel relay output, capacity: 10A; Power consumption of the whole machine: Static current: ≤ 10MA Pull-in current: ≤ 65MA.
【W1209 Features】Fully machine-mounted, wave soldering, stable performance, good consistency; Embedded processor chip (MCU), smarter, lower power consumption; Automatic memory of power-off settings (MCU built-in EEPROM storage unit); Control accuracy 0.1 degrees Celsius; Hysteresis 0.1 settings, can control decimals (0.1-15.0).
【High current relay】The output of the thermostat is a 20A relay, which can meet various high-power loads. After connecting the control circuit, the thermostat can be powered. At this time, the display shows the ambient temperature.
【Waterproof NTC Probe】The NTC probe is waterproof and can control the temperature, allowing to control heating or cooling. With dedicated case（Note: Note: The wood laminate case is the clear plastic case. You need to tear the wood outside layer off carefully, the outside layer is very thin and you need to assemble and install the case by yourself）.
【Indicator, digital tube and buzzer status description】 Indicator: Flashing indicates cooling or heating start delay, constant light indicates relay is closed; Digital tube: Display LL means sensor is open circuit, please connect the sensor according to the instructions; Display HH means the thermostat will forcibly disconnect the relay if the measurement range is exceeded; Display --- means high temperature alarm.
