General InterestSMAKN® DC 24V 2-Channel Voltage Comparator LM393 Comparator ModuleDescription*Functional one: a voltage input to the set on the module reference voltage (reference voltage can be set via an adjustable potentiometer) In contrast, when the input voltage is greater than the reference voltage, the relay closes the circuit connected; when the input voltage is less than the reference voltage, relay off, the circuit is disconnected.
*Function two: two to be compared are input voltage signal A and B, when the voltage is greater than the voltage signal A Signal B, each relay is closed, the circuit is turned on; when the voltage is less than the voltage signal A Signal B, each relay off, the circuit is disconnected .
*Function three: the function of a function is inverted, disconnect the jumper shown in the schematic diagram and short back short contacts. Enter a voltage set on the module reference voltage (reference voltage can be set via an adjustable potentiometer) In contrast, when the input voltage is less than the reference voltage, the relay is closed, the circuit is turned on; when the input voltage is greater than the reference voltage, relay off, the circuit is disconnected.
*Reference: the reference voltage of the module is the input voltage through the multi-turn precision potentiometer voltage obtained by dividing the input voltage determines the range of values of the reference voltage. For example, the input voltage is 12V, then the adjustable reference voltage range is 0-12V.
Parameters: *Working voltage: DC24V.
*Typical operating current (relay together attracted state): DC24V 28mA.
*Standby current (relay engagement portion off): Approximately 5uA.
*Modules Use: Automotive circuit modification, industrial equipment, pilot testing, application testing circuit. FEATURES
