Calculation
The SmartSlice I/O power supply is limited to a total current consumption of 4 A.
This power limit is related to the connected Inputs and Outputs. If the limit is exceeded it is required to
add one or more additional power supplies.
Calculate required addition of Power Supplies.
The maximum I/O current consumption is 4 A.
1
Calculate the total current consumption.
Calculate all external I/O of all connected SmartSlice I/O Units, this includes other Units like
Turnback Units.
Refer to the
GRT1 Series SmartSlice I/O Units Operation Manual
(W455) for the current value
of each SmartSlice I/O Unit.
Reference
The current consumption calculation is important for actual occuring current consumption.
If I/O can not be activated simultaniously this can influence the calculation.
Contact Field Automation certified engineers for more details.
2
If the current consumption exceeds 4 A provide a separate external I/O power supply.
(1) An external I/O power supply can be mounted between SmartSlice I/O Units.
OMRON advises the GRT1-PD2(G) I/O Power Supply Unit for this situation.
(2) External power supplies can also be connected to a Left Turnback Unit (GRT1-TBL).
The GRT1-TBL is equipped with separate power supply terminals for the Unit power
supply and I/O power supply.
Reference
•
Creating separate hardware groups for (groups of) inputs and (groups of) outputs can also be
a reason to separate the SmartSlice I/O Units.
•
Always use isolated power supplies for the power supplies.
•
Power is not supplied through the GCN2-100 Turnback Cable (Refer to the
Wiring Example
)
