    Product Introduction
    Description:
    The module name: 1/2/4 Channel comparison module
    Features: through the comparison of the two voltage to the control circuit on or off by
    Function description:
    1. Function: 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 greater than the reference voltage, the relay is closed (10-9 closed, 10-11 disconnected), when the input voltage is less than the reference voltage, the relay does not operate.
    2. Function two: two to compare respectively input voltage signals A and B, when the voltage signal A is greater than the voltage signal B, the relay is closed (10-9 closed, 10-11 disconnected), when the voltage signal A is less than B voltage signal, the relay does not work.
    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:
    Working voltage: DC DC5V, 12V, 24V
    Working current: DC5V: 350ma, DC12V: 200ma, DC24V: 150ma
    Package Included:
    1 x Comparison Module (Depends on your choice!)
