Description
Description
Set the upper and lower limit voltage on the module, input the sampling voltage from [3] or [4],
when the input voltage value is within the set upper and lower limits Within the voltage range, the relay is closed.
When the input voltage of [3] or [4] is greater than or less than the set upper or lower limit voltage, the relay is turned off.
Upper and lower limit voltage:
After the upper and lower limit voltage is set, it is not affected by the voltage change of the module power supply [1-2], adjustable range is 0-32V.
Module use:
industrial control,
constant temperature
control,
solar charge protection,
battery charge and discharge control
Working voltage:
DC4.5 ~ 28V
Working current:
80ma
Size:
71×48.5x20mm (length x width x height)
