1 CHANNEL RELAY MODULE - TEMPERATURE SENSOR

1 CHANNEL RELAY MODULE - TEMPERATURE SENSOR

The module can be used as an ambient temperature detection. It can be adjusted by the potentiometer to detect the
temperature threshold. It has its own relay and can be used to make various temperature detection switches, such as
indoor temperature monitoring, chassis temperature monitoring, and vehicle temperature monitoring.

Features

1, using high-sensitivity thermistor to detect the ambient temperature, comes with genuine high-quality relay, can
directly control AC or DC load, normally open interface maximum load capacity: AC 0V-250V/10A, DC 0V-30V/10A;

2. The temperature threshold can be adjusted by the potentiometer. When the ambient temperature is higher than
the threshold, the relay is closed, and when the temperature is lower than the threshold, the relay is released;

3. Intelligent adjustment design, when the relay is activated, automatically fine-tune the action threshold to solve
the problem of repeated action of the critical value;

4, the module has anti-reverse connection function, reverse power supply will not damage the module;

5, equipped with power indicator (red), relay status indicator (blue)

6, the module working voltage is 12V

7, with 4 fixing bolt holes for easy installation;

8, module size: 5.0cm * 3.0cm * 1.8cm;

9, the module comes with a free waterproof sensor with 50cm lead

Instructions for use

1. The thermistor module is sensitive to ambient temperature and is generally used to detect changes in the
temperature of the surrounding environment;

2. When the ambient temperature is higher than the set threshold, the relay is closed, the common end is connected
to the normally open end (disconnected from the normally closed end), when the ambient temperature is lower than
the set threshold, the relay is disconnected, the common end Disconnected from the normally open end (connected
to the normally closed end);

3. The common port, normally open, and normally closed ports are equivalent to one dual control switch. When the
relay coil is energized, the common terminal and the normally open terminal are turned on. When there is no power,
the common terminal and the normally closed terminal are turned on;

Electrical parameter

Working voltage: DC 12V

Working current: After the relay is closed: 12V module is less than 40mA

Before the relay is pulled in: less than 2mA

Load capacity: AC 0V--250V/10A, DC 0V--30V/10A
