PLZ series has the capacitor at its DC INPUT side.
If the DC INPUT terminal opens while the load turns off after applying 24 Vdc, the residual voltage is discharged with the high-resistance resistor in the voltmeter of PLZ series, which takes a few seconds until the residual voltage drops to 0 V.
However, if the load has turned on, the residual voltage will be reduced by the set current.
It takes within a few milliseconds (ms) until it drops to 0 V.
(Note: If the low load current is set to flow, the voltage drop time will be longer.)
