*Module name: 4 voltage comparator module*Module size: 93.5 * 64 * 22MM
*Operating voltage: DC 12V
*Working current: 200MA
Product Description:
*Module name: 4 voltage comparator module
*Operating voltage: DC 12V
*Working current: 200MA
*Features: By comparing the two voltage control circuit is turned on or off.
*Module uses: Automotive circuit modification circuit, industrial equipment, pilot testing, application testing and so on. Function description:
*First: 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.
*Second: 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.
