1 Piece - Relay module 12v Thermal Temperature Relay module 12V sensor switch
Temperature detection, adjusting to a valve through the corresponding temperature control potentiometer, with relay output, directly connected to AC power products.
1, automatic temperature control, the temperature is higher than the temperature or below the start, start, select at the output end is connected with the normally open time is higher than the set temperature, is connected with a normally closed below the set temperature start;
2, the comparator output directly drive relays, or other equipment can be connected with 220V ac;
3, with temperature adjustment potentiometer;
4, the sensor interface can be installed with pin, thermal sensor wire;
5, size: 50x26mm, thickness of 19mm, with 4 3mm fixed bolt holes, easy to install.
Power supply voltage: 12VDC
Current: more than 150mA
Load: 10A 250V AC or 10A 30V DC
1, the thermistor module is the most sensitive to environmental temperature, generally used to detect the ambient temperature, the replacement of waterproof thermal sensor can detect temperature.
2, module at ambient temperature over threshold, a relay, a public end and often start connected, and when the ambient temperature is lower than the set threshold, relay disconnect, public ends with the normally closed terminal is connected.
3, the public side, normally open and normally closed three ports is equivalent to a double control switch, the relay coil is energized, the public often start end and conduction, no electricity, public end end communicated with the normally closed;
The temperature sensor and the relay module 1, with thermistor
The water temperature monitoring, indoor temperature monitoring, temperature monitoring car.
