Detail
The setting voltage reference input of a voltage and on the module
(reference voltage can be set through the adjustable resistor) the contrast,
when the input voltage is greater than the reference voltage, the relay is closed
(11-10 closed, 11-12 disconnected), when the input voltage is less than the reference voltage,
relay does not operate.
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 (11-10 closed, 11-12 disconnected), when the voltage signal
A is less than B voltage signal, relay.
The setting voltage reference input of a voltage and on the module (reference voltage can be set
through the adjustable resistor) the contrast, when the input voltage is less than the reference voltage,
the relay is closed (11-10 closed, 11-12 disconnected), when the input voltage is greater than the
reference voltage, after the electric appliance does not work.
The reference voltage:
Voltage reference module (1 or 2-3 input voltage value) after precision resistor divider, input
voltage value determines the range of the reference voltage value, such as the input voltage is 12V,
then the reference voltage adjustable range is 0-12V.
Module purpose:
The automobile circuit hardware, industrial equipment, laboratory testing, application testing circuit.
Specification:
Working voltage: DC24V.
Working current: DC24V 28mA.
Color:as the picture.
Size:63*38mm
