The module name: 4 voltage comparison module
Features: through the comparison of the two voltage to the control circuit on or off by
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
