Relay detecting means

The utility model relates to a detection device. The utility model provides a relay detection device to solve the problem that a relay cannot be detected completely. A magnetic switch, a power supply module and a temperature detection device are arranged in a casing. A coil detection window, a temperature detection window, a normally open/normally closed switch detection window, an indicating lamp One and an indicating lamp Two are arranged on the surface of the casing. The temperature detection device is arranged in the temperature detection window, and is connected with a data acquisition module. The data acquisition module is connected with a processing module, and the processing module is connected with an alarm module. The positive electrode of the power supply module is connected with the input end of the indicating lamp One and the input end of the indicating lamp Two. The output end of the indicating lamp One is connected with one end of the magnetic switch, the other end of the magnetic switch is connected with the negative electrode of the power module, and the magnetic switch is arranged in the coil detection window. The output end of the indicating lamp Two and the negative electrode of the power supply are arranged in the normally open/normally closed switch detection window. The relay detection device of the utility model is applicable to relay detection.
