The power supply for I/O devices is supplied through the PROFIBUS Commu-
nication Unit's screwless clamping power supply terminals. If pin terminals are
used on the wire ends, the pin terminals can be inserted to wire the power.
These terminals supply power to the
external I/O devices connected to the
SmartSlice I/O Units.
Note The GRT1-TBL Left Turnback Unit and GRT1-PD2 I/O Power Supply Unit
have the same screwless clamping power supply terminals. These terminals
are wired in the same way as the PROFIBUS Communication Unit's termi-
nals, by inserting the power supply wires.
To remove the wires press the release button above the terminal hole using a
slotted precision screwdriver and pull out the wire.

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 Vr.m.s and a 42.4-V peak or maximum of 60 VDC.
Recommended power supply: S82K-01524 (OMRON) or S8TS-06024
(OMRON).
