Example of current consumption/power calculations for ML200R
This section describes which power supply module must be used in coordination with the
corresponding modules for ML200R.
Main base
Type Model Quantity Voltage (5V)
CPU Module 2MLR-CPUH/F 1 1.31A
Main Base 2MLR-M02P 1 0.2A
2MLR-M06P 1 0.2A 2MLR-M06P
CPU Module 2MLR-CPUH/F 1 1.31A
Current Consumption / Power
Consumption
1.31A + 0.61A∗6 = 4.97A/4.97×5V =
24.85W
Expansion base
Type Model Quantity Voltage (5V)
Expansion
Driver
2MLR-DBSF 1 0.65A
Expansion
Base
2MLR-E12P 1 0.21 A
DI Module 2MLI-D24A 2 0.05A
DO Module 2MLQ-RY2A 6 0.5A
AI Module 2MLF-AD4S 2 0.61A
Profibus-DP 2MLL-PMEA 2 0.56A
Current Consumption/Power
Consumption
0.65A + 0.05A∗2 + 0.5A∗6 + 0.61A∗2 + 0.56A∗2 =
6.09ª / 6.09A × 5V = 30.85 W
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.
