Why the low voltage at both ends of the circuit board relay coil cannot make the coil pull in?

Is your applied voltage lower than the voltage that the relay can absorb.

Of course, it will be released under voltage if it is lower than the minimum maintenance voltage of the relay.

If the voltage is too low, the power of the coil will be insufficient.

First, check whether the voltage is lower than the voltage that the relay can absorb. If not, check whether the coil resistance is normal.
