Three features: the setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) comparison, when the input voltage is less than the reference voltage, the relay is closed (10-9 ratio, 11-10 disconnected), when the input voltage is greater than the reference voltage, the relay does not operate. The reference voltage: This version upgrades for the enhanced version 4 voltage comparator module, add the reference voltage stabilizing circuit, a reference voltage is not receiving module power supply voltage change, adjustable reference voltage range can reach 0-31V. Module purpose: the automobile circuit hardware, industrial equipment, laboratory testing, application Testing circuit :DC 12V Working current: DC5V:350ma, DC12V:200ma, DC24V:150ma Package Included: 1PC*12V Module.Find many great new \u0026amp; used options and get the best deals for DC 12V LM393 Stable Comparator Module 4 Channel Voltage Development Board Module at the best online prices at Order2india Shopping!
