Current Consumption/Power
Consumption
Sum of current consumption is 6.17A. Hence, use 2MLR-AC13 or 2MLR-AC23.
ATTENTION
Maximum power consumption of PLC can be derived from the efficiency of power module.
Example: Sum of 5V consumption x Minimum efficiency of Power module = 100W/0.65 = 154W.
The following figure illustrates the method used for calculating the current consumption of the PLC
system necessary for heat protection design.
