Note: This module is used for 50HZ AC current measurement, and is suitable for measuring the situation where the current waveform is not seriously distorted, otherwise the error will increase.
Note: the internal diameter of 50A transformer is 8mm.
This module can realize the measurement and display of AC current, and can set upper current upper and lower alarm output, base current measurement and display range from 00.0A to 60.0A (selected 50A transformer) /0.00A to 6.00A (selected 5A transformer), and the measurement accuracy is 1%. Power supply anti - reverse function.
Power interface: DC 5V, 12V, 24V three versions are optional.
Module current measurement range: AC 00.0A to 60.0A (50A transformer), /0.00A to 6.00A (optional 5A transformer)
Relay action upper limit setting voltage range: 0.1A ~ 60.0A /0.01A to 6.00A note: set 0.0A to cancel the overcurrent action function.
Relay action lower limit set current range: 0.1A ~ 59.9A/0.01A ~ 5.99A note: set 0.0A to cancel overcurrent action function.
Relay action start time: 0.1S to 9.9S
Relay action time: 1S to 99S or self locking (set).
Digital tube display: open / close
Figure 1 product functional interface description
Relay output: normally open and normally closed interface, which facilitates the application of various occasions.
Input of mutual inductor: /5A transformer with 50A transformer
Setting key: enter the set mode when the long press button is set.
Add - button: for parameter setting.
Subtracting key: for parameter setting.
Parameter setting method and Parameter Description:
The module size is shown in Figure 2. The display of the measurement status is shown in Figure 3.
Upper limit of current setting
According to the "set" key, you will enter the over flow setting mode and the digital tube will flicker. As shown in Figure 4, this time set is the upper limit current value of the relay action, and the value is set by "add" the "minus" key, and the relay action is over when the current exceeds the set value. When the current value is set to 0.0A, the digital tube will show the information shown in Figure 5, and the over current protection function of the module will be cancelled, and the relay will not act by over current.
Lower current setting
The second time press "set" key to enter the current lower limit alarm setting mode, the digital tube will flicker, as shown in Figure 6: this time the set is the relay action lower current value, by "add" the "minus" key set the value, when the current is lower than the set value, the relay action. When the current value is set to 0.0A, the digital tube will show the information shown in Figure 7, at this time the module's undercurrent protection function will be cancelled, and the relay will not act due to the undercurrent.
Relay start time setting
After the third press "set" key, enter the relay action start time setting, the digital tube will flicker, as shown in Figure 8: this time set the relay action start time value, set range: 0.1S to 9.9S, set this value by "add" the "minus" key, when the current exceeds or is lower than the set value, the relay will delay the set Post time action
Relay action hold time setting
After the fourth press "set" key, enter the relay action retention time setting, the digital tube will flicker, as shown in Figure 9: this time set is the relay action keep time value, setting range: 1S to 99S, by "add" the "minus" key set the value, relay will delay after the setting time after the reset. And when the set value is 99S, then press the "add" key, then the information of Figure 10 will be displayed, then the relay action hold time will be extended indefinitely, that is, after the action, it will lock itself until the module is broken to reset.
Finally, press the set button once, and then you can exit the setting mode, enter the measurement mode, and save data at the same time, and the data can still be saved after power failure.
Digital tube display opening / closing operation
The default digital tube is opened for display each time. Sometimes for low power requirements or for environmental needs, the display needs to be closed. At this time, only the "display / turn" button (used as "subtraction") in the middle of the three buttons is needed to close the digital tube display.
When you need to turn on the digital display, you just need to press the button again, and the digital tube can reopen the display.
