4.4 Calculation Example of Consumption Current/Voltage
Calculate the consumption current and configure the system not to exceed the output current capacity of
basic unit.
(1) XGB PLC configuration example 1
Consumption of current/voltage is calculated as follows.
Type Model Unit No.
Internal 5V
consumption
current
(Unit :
㎃
)
Remark
Main unit XBC-DN20S 1 240
In case contact points are On.
(Maximum consumption current)
Expansion
module
XBE-DC32A 2 50
XBE-TN32A 2 80
XBF-AD04A 1 120
All channel is used.
(Maximum consumption current)
XBF-DC04A 1 110
XBL-C21A 1 110

Consumption
voltage
4.25 W 0.85 * 5V = 4.25W
In case system is configured as above, since 5V consumption current is total 850mA and 5V output of XGB
standard type main unit is maximum 1.5A, normal system configuration is available.
(2) XGB PLC configuration example 2
Type Model Unit No.

Consumption
voltage
9.925 W
1.985ⅹ 5V = 9.925W
If system is configured as above, total 5V current consumption is exceeded 1,985 mA and it exceeds the 5V
output of XGB standard type main unit. Normal system configuration is not available. Although we assume
the above example that all contact points are on, please use high-end type main unit which 5V output
capacity is higher than standard type main unit.
