Current detection module specification_20A V1.3 This module is used for detecting current in an AC circuit, and through digital tube display, set the current threshold and the relay delay time through the button, when the detected current reaches the set value, the relay and the delay time for the set time. Calibration method:1. Module power, the clockwise direction, adjust the RP2 potentiometer so that digital control on the emergence of digital control, and then slowly adjust the potentiometer, the digital control of the digital display is just 000.2. By adjusting the RP1 potentiometer, the value of the digital tube can be determined by adjusting the value of the current. working voltage DC 24V±0.5V.Working current:Before protection less than equal 30mA,After protection less than equal 60mA.Detection range AC 0-20A.detection accuracy Max ±0.2A.Output Switch quantity (Relay output).Size Modules 72mm*69mm*23mm.Belt guide 89mm*71.5mm*55mm Debugging method 1. Current threshold setting Long release press SET 3S, digital tube flashing into the state, at this time for the current threshold setting state, through the + key and - key to set by clicking the SET button to change settings. After setup is complete, press the SET button about 3S when release this button, the digital tube flashing out of state. The setting was saved successfully. (The default threshold for the 10A. but because of the precision, min of not less than 0.2A and the highest is not higher than 19.8A) 2. Output delay time setting Loosen the long press SET 7S, digital tube flashing into the state, at this time for the output delay time setting state, through the + key and key to - time setting, change settings by clicking on the SET button. After setup is complete, press the SET button about 3S when release this button, the digital tube flashing out state settings success. (The longest delay time can be set to 99.9S, the default 3S) Note The potentiometer on the module is used in the factory , all the modules have been adjusted before they leave the factory. Please do not adjust it. If the error exceeds the precision after long term operation, calibrate it according to the calibration method. colour:green + black Material:ABS + electronic components Package Contents: 1 x Current sensor with base 1 x Manual Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
