Temperature measurement, through the potentiometer to adjust to a point, control the corresponding temperature, with the relay output, direct access to the exchange of high power products.
1, automatic control temperature, lower than the start temperature, or higher than the temperature, the choice of the output side is higher than the set temperature is set to start, then normally closed is lower than the set temperature to start;
2, the comparator outputs a direct drive relay, can be connected to 220V AC or other equipment;
3, with potentiometer adjustment temperature;
4, the sensor interface can be installed with pin, thermal sensor wire;
5, the overall size is: 50x26mm, thick 19mm, with 4 3mm fixed bolt holes, easy to install.
Power supply voltage: 5VDC
Current: more than 150mA
Load: 10A 250V AC or 10A 30V DC
1, thermal resistance module is the most sensitive to the ambient temperature, generally used to detect the temperature of the surrounding environment, the replacement of waterproof thermal sensor can detect the water 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, normally closed three ports is equivalent to a double control switch, relay coil power, the public and often start conducting, without electricity, the public and the normally closed end;
Temperature sensor and relay module 1, with a thermistor
Examples of product use:
Water tank temperature monitoring, indoor temperature monitoring, vehicle temperature monitoring, etc..
When the environment temperature is higher than the preset temperature, relay, bright lighting, is lower than the set temperature, relay disconnect, bright lights (shown only said wiring method), grounding for high voltage method.
When the environment temperature is higher than the preset temperature, relay, bright lighting, is lower than the set temperature, relay disconnect, bright lights (shown only said wiring method), for common power supply connection.
