Installing the Turnback Units
Note
You can use Turnback Units to expand or divide a SmartSlice I/O Terminal.
Install a Right Turnback Unit (GRT1-TBR) on the right side of the block. Install
a Left Turnback Unit (GRT1-TBL) on the left side of the expansion or divided
block. Then install the necessary SmartSlice I/O Units.
Connect the Right Turnback Unit to the Left Turnback Unit with a Turnback
Cable (GCN2-100). (Refer to
Connecting the Turnback Cables
on page 35.)
There can be three blocks in a SmartSlice I/O Terminal, one main block and
two expansion blocks.

• You must install an End Unit (GRT1-END) on the end of the last block in the
SmartSlice I/O Terminal.
• There are limits for each block to the capacity of the Unit power supply and the
I/O power supply. If the Unit power consumption of the SmartSlice I/O Units in
one block is higher than 80 W, you must divide the SmartSlice I/O Terminal.
Refer to
Precautions When Connecting the Power Supplies
on page 36 for
