Description : Current Detection Range : DC 0 - 10A ; Dimension : 89x71 . 5x50mm / 3 . 5x2 . 8x1 . 97in DC current detection digital display sensor module It is used to detect the current value in the DC circuits and output the corresponding linear voltage value and display the current value through the digital tube . If the current exceeds the preset value , the relay on the module acts and delays recovery , which can avoid the current fluctuation time . It is convenient for direct controlling of equipment switch and achieve automatic control . Specification : Working Temperature : 0 - 65 ( Need to customize - 40 ~ 75 C , please contact online customer service ) Humidity Range : 10 ~ 95 % RH ( no condensation ) Analog Signal : 0 - 10V Installation Method : as picture shown Switch Signal : relay output , the fastest response time ( 300mS ) Delay Time Setting : delay time setting range : 0 - 99 . 9S , module default value : 3S With base : C45 standard rail Threshold current and delay time setting method : 1 . Press and hold the SET button for 3 - 5 seconds to release , and the digital tube enters the threshold current setting state . The last digit of the digital tube is blinking . 2 . Use the + or - key to set the threshold current , and click the SET key to perform the transposition ( that is , the flashing state is forward one ) 3 . After the setting is completed , press and hold the SET button for 3 - 5 seconds and release it . The digital tube returns to the initial screen ( 000 ), indicating that the setting was successful . 4 . Hold down the SET key and the module will automatically enter the time setting interface . Refer to 6 . 2 and 6 . 3 for setting method . ( The default interface for time setting is : 03 . 0 ) Package Includes : 1 piece current detection module
