DC 12V 4-Channel Voltage Comparator Stable LM393 Comparator Module

 


Description:

The module name: 4 voltage 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 is S

less 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
