W1209 12V -50-110°C Digital Thermostat Temperature Control Switch Sensor + Case
W1209 12V -50°C to +110°C(-58 F to +230 F)Digital Thermostat Temperature Control Switch Sensor Module With Acrylic Enclosure Case
The W1209 is a low cost yet highly functional thermostat controller with aclear acrylic plastic enclosure. This module intelligently controls power to most types of electrical devices based on the temperature sensed by the included high accuracy NTC remote temperature sensor.The cooler, heater or fan is connected to a power supply through the relay contacts K0 and K1, and the temperature on/off setpoints are programmed into the W1209 using the onboard Set, Increase and Decrease buttons and display. The relay contacts are then open and closed, acting as a power switch for the cooler/heater, based on the temperature measuredby the NTC temperature sensor (included with the module) and the setpoints programmed into the W1209 controller.
Although this module has an embedded microcontroller, no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on-board relay can switch up to a maximum of 20A at 14V DC, 16A at 24V DC, or 7A at 125V AC. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
Specifications:
- Temperature Control Range: -50 C to +110 C (-58 F to +230 F)(NOTE: All temperatures are in Celsius, not Fahrenheit)
- Resolution at -9.9 to 99.9: 0.1 C
- Resolution at all other temperatures: 1 C
- Measurement Accuracy: 0.1 C
- Control Accuracy: 0.1 C
- Refresh Rate: 0.5 Seconds
- Input Power (DC): 6V to 12V @ 65mA maximum (Provides power for the module, not the load)
NOTE: The maximum input support voltage should not exceed 12V. In applications such as an automobile or RV where the battery voltage can exceed 12V, a regulator circuit such as a 1N5349A zener diode and a series resistor in the range of 20 Ohm 1W should be used to limit the voltage to 12V. Alternately, a 12V to 9V buck voltage converterwith the input to the converter connected to the battery and the output to the W1209 will provide a stable 9V DC supply for the W1209. - Measuring Input: NTC (10K 0.5%)
- Waterproof Sensor: 0.5M cable
- Probe tip dimensions: 20mm long x 4mm diameter
- Output: 1 Channel Relay Output, Capacity: 20A at 14V DC, 16A at 24V DC, or 7A at 125V AC
- Includes a Clear Acrylic Case (Box) with mounting screws (assembly required)
Power Consumption:
- Static Current: <=35mA
- Operating Current: <=65mA
Environmental Requirements:
- Temperature: -10 ~ 60 C
