Wiring the GRT1-PRT
Section 2-3
Supplying I/O Power
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.
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.
Removing Wires To remove the wires press the release button above the terminal hole using a
slotted precision screwdriver and pull out the wire.
Recommended Power
Supplies 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).
Recommended Wire
Strip Length
Pin Terminal Length Strip wire between 7 and 10 mm of insulation at the ends of the wires
(stranded or solid wire) or use pin terminals with a pin (conductor) length of 8
to 10 mm.
These terminals supply power to the
external I/O devices connected to the
SmartSlice I/O Units.
