4.4 Calculation Example of Consumption Current/Voltage
Calculate the consumption current and configure the system not to exceed the output current capacity of main
unit.
(1) XGB PLC configuration example 1
Consumption of current/voltage is calculated as follows.
Type Model Unit No.
Internal 5V

Remark
Main unit XEC-DN32H 1 260
In case contact points are On.

0.87A ⅹ 5V = 4.35W
In case system is configured as above, since 5V consumption current is total 870 mA and 5V output of XGB 32
points main unit is maximum 2A, normal system configuration is available.

If system is configured as above, total 5V current consumption is exceeded 2,310mA and it exceeds the 5V output
of XGB 32 points main unit. Normal system configuration is not available. Although we assume the above
example that all contact points are on, please use 64 points main unit which 5V output capacity is higher than
standard type main unit.
