W1209 24V -50°C to +110°C Digital Thermostat Temperature Control Switch Sensor Module The W1209 is a low cost yet highly functional thermostat controller. 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 (either DC or AC) 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 measured by the NTC temperature sensor (included with the module) and the setpoints programmed into the W1209 controller. A 24V DC power supply or battery powers the module. 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 16V DC, or 10A 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 (NOTE: All temperatures are in Celsius, not Fahrenheit)Resolution at -9.9 to 99.9: 0.1 CResolution at all other temperatures: 1 CMeasurement Accuracy: 0.1 CControl Accuracy: 0.1 CRefresh Rate: 0.5 SecondsInput Support Power (DC): 24V. The maximum current draw is 65mA (operates the module, does not power the load). NOTE: The maximum input support voltage should not exceed 24V +/-10%. The silkscreen on the circuit board input is marked 12V, but the input for this model is 24V, not 12V. The voltage marked on the relay indicates the module's actual voltage.
