Voltage fluctuation
Ripple noise
24VDC voltage may drop instantaneously due to rush current at the beginning of 24V power
supply to the operation panel I/O unit. The level of voltage drop depends on the capacity of the
power supply. Do not share the power supply with the devices that have alarms to warn the
voltage drop.
Standard setting
±5% or less of 24VDC
200mV (P-P)
Calculate the current value as a reference of maximum current
consumption for the unit which uses the power supply.
