Power Supply Wiring
Section 3-2
Power Consumption of Slice I/O Units
Refer to
Appendix E I/O Current Consumption
for the power consumption of
the various Slice I/O Units and Turnback Units.
Note
When dividing the power supply, always wire (supply) the power from the
same power supply. (Refer to the following wiring example.)
I/O Power Supply
The maximum I/O current consumption is 4 A.
1,2,3...
1.
Calculate the total current consumption used by all external I/O of the con-
nected Slice I/O Units (including other Units such as Turnback Units).
2.
If the current consumption exceeds 4 A or you want to provide separate
systems for inputs and outputs, divide the Slice I/O Units at the desired
point with a GRT1-PD2 I/O Power Supply Unit and provide a separate ex-
ternal I/O power supply.
3.
It is also possible to provide a separate external I/O power supply at a Left
Turnback Unit (GRT1-TBL).
Current Consumption for Slice I/O Unit I/O
Refer to
Appendix D Power Consumption Tables
for the I/O current consump-
tion of the various Slice I/O Units and Turnback Units.
Note
(1) Always use isolated power supplies for the power supplies.
(2) Power is not supplied through the GCN2-100 Turnback Cable.
(Refer to the following wiring example.)

Wiring Methods
Supplying Power to
the Units
Connect the power supply wires (24 VDC) to the DeviceNet Communications
Unit’s screwless clamping power supply terminals. If pin terminals are used on
the wire ends, the pin terminals can just be inserted to wire the power.
