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
connected SmartSlice I/O Units (including other Units like the Memory End
Unit). Refer to the GRT1 Series SmartSlice I/O Units Operation Manual
(W455) for the (maximum) current value for each SmartSlice I/O Unit.
2 If the current consumption exceeds 4 A or you want to provide separate
systems for inputs and outputs, divide the SmartSlice I/O Units at the
desired point with a GRT1-PD2 I/O Power Supply Unit and provide a
separate external 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).
Note 1 The GRT1-TBL is equipped with separate power supply terminals for the Unit power
supply and I/O power supply.
2 Always use isolated power supplies for the power supplies.
3 Power is not supplied through the GCN2-100 Turnback Cable from one block to the
next, as shown in the wiring example above.
Connect the power supply wires (24 V
Communication Unit's screwless clamping power supply terminals. Apply pin
terminals to the wire ends before inserting them in the wire terminals.
Use a SELV power supply with over current protection.
A SELV power supply has redundant or increased insulation between the I/O,
an output voltage of 30 V
Recommended power supply: S82K-01524 (OMRON) or S8TS-06024
(OMRON).
