Solenoid valve
Note: The connection terminal of solenoid valve/contactor cannot be connected to other load. When
the power of solenoid valve and contactor coil exceeds 30W, the power frequency transformer inside
the integrated machine needs to be customized or connected with external 220V power
independently.
