It employs a PLC industrial control board for programming, controlling relay engagement to achieve power-on / off functionality. Four DIP switches are used to control four different power-on / off cycles on the PLC industrial control board. Furthermore, a counter displays the number of power-on / off cycles; when the target number is reached, the process automatically terminates with an audible and visual alarm. The entire device features 3 inputs and 10 outputs.

[0005] The specific plan is as follows: A current sensor on / off testing device includes an external housing. The top surface of the housing is equipped with a power switch, a counter, LED indicators, a buzzer, and four test range switches. The front side has multiple output terminals, and the rear side has multiple input terminals. Internally, it houses a PLC control board, a switching power supply, and four sets of relays. A regulated power supply is input through the input terminals and connected to the output terminals via the four sets of relays. The output terminals are connected to the product under test. The four test range switches are connected to the corresponding four sets of relays via the PLC control board. The switching power supply is connected to the PLC control board. The counter, LED indicators, and buzzer are connected to the four sets of relays. The power switch is connected to the switching power supply.

[0006] Furthermore, the four test position switches include test position switch one, test position switch two, test position switch three and test position switch four, which correspond to 1000, 2000, 5000 and 10000 power-on / off cycles, respectively.

[0007] Furthermore, the four sets of relays include relay one, relay two, relay three, and relay four.

[0008] Furthermore, there are 3 input terminals and 10 sets of output terminals, with each set of 3 terminals connected to the positive and negative ground of the product respectively.

[0009] Furthermore, a cooling fan is also provided on the rear side of the external housing.

[0010] The beneficial effects of this application are as follows: This device boasts a novel and unique structure, reliable testing capabilities, and high efficiency. It can test up to 10 products simultaneously, significantly increasing production capacity and reducing costs. The PLC control board allows for precise control of power-on / off time and frequency.

Detailed Implementation

[0014] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0015] As shown in the figure, this application provides a current sensor on / off testing device, including an external housing 1. The top surface of the external housing 1 is equipped with a power switch 3, a counter 5, an LED indicator 6, a buzzer 7, and four test range switches. The front side is equipped with multiple output terminals 2, and the rear side is equipped with multiple input terminals 10. The interior is equipped with a PLC industrial control board 9, a switching power supply 11, and four sets of relays. The regulated power supply is input through the input terminals 10 and connected to the output terminals 2 via the four sets of relays. The output terminals are connected to the product under test. The four test range switches are connected to the corresponding four sets of relays through the PLC industrial control board 9. The switching power supply 11 is connected to the PLC industrial control board 9. The counter 5, LED indicator 6, and buzzer 7 are connected to the four sets of relays. The power switch 3 is connected to the switching power supply 11.

[0016] In this embodiment, the four test position switches include test position switch one 4-1, test position switch two 4-2, test position switch three 4-3, and test position switch four 4-4, corresponding to 1000, 2000, 5000, and 10000 power-on / off cycles, respectively. The four sets of relays include relay one 8-1, relay two 8-2, relay three 8-3, and relay four 8-4.

[0017] In this embodiment, there are 3 input terminals and 10 sets of output terminals, with each set of 3 terminals connected to the positive and negative ground of the product respectively.

[0018] In this embodiment, a cooling fan 12 is also provided on the rear side of the outer casing 1.

[0019] The working steps of this application are as follows: 1) Connect the input terminal to a regulated power supply, and set the regulated power supply to the product's operating voltage.

[0020] 2) Input 220V AC mains power to the switching power supply and turn on the power switch to power on the test device.

[0021] 3) Connect the output terminals to the positive and negative ground of the product under test, and select test range switches one through four according to the experimental outline to perform the same number of cycles. For example, if the power is turned on and off 1000 times, select test range switch one and turn it on.

[0022] 4) The counter starts counting. The LED indicator light stays on when the power is on and turns off when the power is off.

[0023] 5) A cycle of 60 seconds on and 60 seconds off constitutes one cycle, and the counter value increments by 1.

[0024] 6) For example, when the cycle reaches 1000 times, the counter counts to 1000 and the test device automatically stops, and the buzzer sounds an alarm.

[0025] 7) Turn off test mode switch one and turn off the power switch to end the test.

[0026] The working principle of this application is as follows: Write four different switching cycles (1000, 2000, 5000, and 10000) onto the PLC industrial control board.

[0027] 2) By testing the different interfaces within the PLC industrial control board controlled by gear switches one to four, the program controls the activation of relays one to four by outputting different switching times, thereby realizing the power on / off of the product connected to the output terminal.

[0028] 3) The counter counts by the activation of the relay.

[0029] 4) The LED indicator light is connected to the relay. When the relay is energized, the light remains on; when the relay is de-energized, the light turns off. This allows for a direct assessment of the device's operating status.

[0030] 5) The buzzer is connected to the relay to trigger an alarm after a specified number of power cycles, indicating to the staff that the test is complete.

[0031] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
